Help with block tick update 1.16.5

So i'm using versoin 2022.3 mcreator with a generator for 1.16.5

I'm trying to make a block that converts to another block then it waits a minute before turning back

i manage to do the convert thing on player distroy -> spawn item -> replace block with 

so now im struggling with converting the block back i tried doing with trigger when block is added
that it (waits 1200 ticks -> convert block) this way worked fine but when i leave and rejoin when the block was still not converted it will not convert back anymore no matter how many ticks have passed 

i tried even doing the random tick thing in advenced options and update tick  trigger but then it would not work at all anymore and  would complety break  

i am hoping someone could help me with this?  (will send producre if needed to look at)
