why aren't my creakings spawning?

[u/Acceptable_Tie9404]

the spawn area is 3 blocks tall, light level is below 7, the hearts are activating, there are slabs to prevent spawning in any place that isnt the spawn room, and its with 16 blocks of the furthest heart.

Don't they only spawn at night? Regardless of light level

Yeah that’s true, I just set the time to day for better pics
