Wait Procedure not working on blocks.

I have recently been in the process of updating my mod The Arcaneum from 1.16.5 to 1.20.4. The code for my altar blocks worked in 1.16.5 but has stopped working since updating to 1.20.4

I have been able to deduce that this code works when I remove the "wait 45 ticks" code block. I use similar code blocks to this that utilize the "wait block" but are attached to items instead of blocks and they work. 

Can anyone explain why this bug seems to only affect blocks? I hope someone can provide me with any possible solutions to the problem. Thank you.
