Using Project Logical Editor or MIDI Logical editor to select things seems to screw things. As if after running the logical editor preset, selections are not updated by Cubase internally.
This is obvious when using Logical Editor presets with macros. You run the macro 5 times and it works, change selection to something else, run the macro, and it will appear that macro is run on things that were previously selected.
If Steinberg Developers need presets and projects that replicate this, please contact me.
Thank you very much! 
edit:
Macros and logical presets that let you see what’s wrong can be found here in my Ripple Editing proof of concept thread:
I suspect all the issues in the above thread have to do with updates to graphics system - also reported it here: Macro and Logical Editor Bugs - Cubase 9.5 - Cubase - Steinberg Forums
