Bug Report strange scene collection window display

[OBSnewby]

Hi, recently I started to notice this strange thing happening on scene collection window: 2 or 3 items selected as main scene collection at the same time... (see attached screenshot)
also Ive noticed that obs didnt save all my recent changes like new added sources or scenes...
Im on 19.0.3 version
should i upload a crash log or something to you to take a proper look?
really thanks!

Ok, Ive made more tests and here is what Ive found

1. If I open a scene collection named PROJECT 1, modify it adding some scenes or sources, and then export it (as a way to save my OBS actual project just in case) and name it as BUCKUP...

Then I go to IMPORT scene collection, select project 1.json and open it... it open only the original project1 file... and duplicate it on my scene window collection (as I show on the screenshot attached...)

Is this a know bug of this version? how to fix it? Im unable to save my changes and my scene window is getting messy...
