Logic Pro Playhead missing

I have recently updated to Monterey using OCLP and the only problem I'm facing is that Logic (10.7.9) will not show the playhead. I have found a thread from 2 years ago that suggest that terminal command "defaults write -g Moraea.LogicPlayheadHack -bool true" which unfortunately didn't work for me. I am still playing with OCLP trying to find the best OS or best solution for my case and I'm open to trying other OS, so any suggestions or opinions are appreciated!

I'm using a mid-2011 21,5" iMac with 1TB SSD and 20GB Ram. I was using High Sierra and updated to Monterey. It works great except for this. I wanted to keep both OSs as startup disks and use HS for Logic only, but many threads suggest High Sierra can't be used with dual startup, apparently it corrupts both systems. Thank you guys so much!
