One clue is that lots of the tab numbers (not the bars) are now highlighted in red, after applying.
hammer-ons are fretted for the initial pick but not the hammer on note, which doesn't make sense?) Seemingly random strings are affected by the capo in a way that doesn't make sense (e.g. I switch off regular capo and turn on partial capo to 4th fret, for every string except 6th, it sounds awful. If I choose regular cap on the 4th fret, the pitch adjusts as expected and all works well, other than the low E string not being accurate due to not wanting it to be fretted. Tuning is standard except for the low E string is turned to a a Db. I want to fret every string with a capo except the the low E string. Googling reveals little evidence of others having this problem but I suppose it's a niche use, so maybe it's not stumbled upon often. Using Guitar Pro 7.5 I can't seem to get partial capo to work as expected.
