Full tab not displaying correctly in v4.1.1

TBH, I'm finding MuseScore 4 horrible compared with MuseScore 3. I mainly use MuseScore to create bass tabs and normally use "Bass Guitar Tablature (Full)". Two issues that seriously affect usability are:
1. Dotted values cannot be selected via the keyboard. In v3, I could (for example) select "dotted crotchet" by pressing 5 then dot on the numeric keypad. This doesn't work with v4.
2. When writing out chords in v3, I select the first note of the bar then press K. MuseScore opens a text box above the stave for the chord. I then type the chord and either press Tab to move to the next bar or Space to move to the next measure. In v4, I am obliged to select a note then press K to open the text box for the chord. Neither Tab nor Space does anything and I need to select another note and press K again to enter another chord.
The above 2 issues alone mean I'm likely to stay with MuseScore 3. However, the real show stopper is that bass tab doesn't display correctly. The attached file shows one bar created in both v3 and v4. The two notes are a dotted crotchet and a minim, but in v4 these look like an undotted crotched followed by a minim. v4 also strips the dots from scores created in v3 -- which is irksome since I'd used v4 to open scores previously created in v3 and then saved without noticing this issue, which is going to cost me hours upon hours to identify the 'mangled' scores and (since there's no option to save in v3 format) recreate them in MuseScore 3.
