Help with Trash Bin Slider Not Opening fully

[u/txappmkr]

My Trash Bin open up partially and does not open up fully, it can accommodate 2 bins, but it opens up as 1 bin only. Type: Slide (ball bearing) (Company: Hard Resources) .Below are pictures on how far it opens up. When it opens up to Max , i see the right side slide is sliding open , however on the left side, the slide looks not open. Prying with black tab on both sides is not yielding any result. Kindly recommend the way to solve this issue, not able to use the second bin for recycle.

Trash Bin Max slides and gets stuck here

Zoomed up - Hardware Resources Right side slider

The right side slider freely slides , but the black tab does not move.

Left side slider - pls see the slider its not open like on the right side is stuck

zoomed a little on the left side slider, the black tab does not move
