Differential Pair set-up broken

On Kicad 9.0.1 on MacOS, setting up defferential pairs seems to be broken. Trying to set custom trace widths and it either doesnt let me place past the first line, changes the trace width/gap after the first click or adds broken tracks for no reason.

Have tried all the interatice router setting(shove/walk around), added widths as a new net class, tried custom values from the router itself, tried another computer. seems its broken accross the board. which isnt great as on a deadline…
