Text mode doesn't work as expected with pasting chords or changing duration

Hello there! I like Hookpad (and pay for it) but I’ve always had issues moving chords over without overwriting which makes things frustrating

Latest Hookpad, with both latest MacOS/Safari and Windows 10/Chrome.

I’ve selected Text mode, which SHOULD slide chords to the right over, but in pasting copied chords or selecting chords and changing duration, nothing pastes or expands from one duration to a longer one.

Needing to micromanage sliding everything over manually/properly to the point where I give up.

Any tips? From reading instructions this should be simple, maybe I’m missing something?

Thank you!
