Short description of error

Hello.
I'm using a custom navigation layout with orbiting assigned to just Left Mouse and most of the other functions that use LMB reassigned to something different to avoid conflicts. I recently installed the new Blender 3.01 and successfully transferred my hotkeys. Most of the custom hotkeys like for modeling commands work fine, but when I have any other tool except the Tweak Tool selected from the left trey (like Move/Rotate/Scale tools), then LMB clicking and orbiting my scene keeps selecting objects/mesh elements that are currently under my cursor. Is there a way to fix it?
PS I use the Blender 2.7 layout as a basis for my current one because I really don't like changes introduced since 2.8
Thank you!
