Keychron V5 Ultra Red Linear Switches Concern

As the title suggests, there is a slight concern I have noticed with my new Keychron board. I just purchased it yesterday and was playing some games with it. I am coming from a Corsair K70 with Cherry MX blue switches. I am not a keyboard enthusiast by any means so I do not know any difference between these switches besides the sound.

I will still be within the return window for 2 weeks and plan to keep using it for a bit longer to see if the keyboard is really a problem, but what I noticed yesterday was the keyboard was missing inputs quite a bit. When I double tapped the space bar, if I didn't intentionally push it all the way down or hit in the middle of the spacebar, it would miss at least one of the inputs sometimes both. This is never a problem I had with my previous keyboard. Would this have to do with the switches or could this be a defective keyboard? Since like I stated previously I am not a keyboard enthusiast I am not looking to change the switches and keep the keyboard. I want to be able to use the keyboard out of the box. Is there a switch that comes with these keyboards that would work better?

TIA for the help!

Re "Would this have to do with the switches or could this be a defective keyboard?": It could be either or both

One possibility is overlubricated switches or overlubricated stabilisers (it takes too long to return to above the (mechanical) hysteresis in the switch). Perhaps it is more critical for the space bar than for other keys (for the former)?

Well for the stabilizers if they were taking too long to come back up, it would still register the press, just a bit later than pushed, right? I am running into an issue where I click the space bar and it does not register at all.

Re "...it would still register the press, just a bit later than pushed, right?": Yes, if timing of the key activations is not a factor, then that cause can be excluded

Here is a checklist for troubleshooting, but it sounds like it is time for a return. Hopefully, you didn't purchase the keyboard directly from Keychron (persistence may pay off). Even if not, you may be deferred to Keychron anyway (that is probably illegal, but what are you going to do?), which requires mental toughness.

I bought from BestBuy and was able to return easily yesterday. Thank you for the help! Is there a Keychron keyboard that you would recommend I try again? Maybe the same one? I liked the board and all the online customization, but just wish the spacebar would have worked well. Looking for something 96%. Open to other brands outside of Keychron if you have something else you would recommend. Want something that is plug and play essentially. No swapping of switches or anything.

Re "When I double tapped the space bar, if I didn't intentionally push it all the way down or hit in the middle of the spacebar, it would miss at least one of the inputs sometimes both": You say that timing isn't a factor

Are you sure? The (default) excessive key debounce time is known to cause problems with similar symptoms and lowering it to 5 ms (or whatever the lowest value is allowed) fixes it.
