ECS Dots console bugs won't let me keep going with it

using Unity 2022.3.8f1 ... I've been trying to switch (starting from a new project) into using ECS but cannot get a clean console -_- I've tried running Unity's tutorial here as well as several other places.

Managed to clean the majority of console warnings / errors etc. but have gotten stuck at 

Leak Detected : Persistent allocates 12 individual allocations.

spending too much time on this and my ocd won't let me keep going with the console Leak Detected message...

going to keep going with the non-ECS build and see if I can add a few more things to have a more polished game.
