Publisher 2: jumps 2mm instead of 1

[Nightjar]

hello 

i'm on affinity publisher 2, yay. most of the things are working great. something thats been bothering me: when i use the arrow in my document the field moves 2mm instead of the 1mm i had in publisher 1. in the preferences "decimal places" in "mm" is set to 1. The weird thing: sometimes it's just 1mm it jumps but mostly two. E.g how it mostly is (distance to another object): 60mm --› 59mm --› 57mm --› 55mm --› 53mm etc. 

Anybody has a clue? 

Thanks for the help! Appreciated.

My first guess is that the values shown are not the actual values.

In other words, the values may have a fractional part which you can’t see and that could be causing the problem, or be a symptom of the problem.

Try going into Preferences / User Interface and changing all of the Decimal Places settings to three or more decimal places and see what happens in the Transform Panel.

Thanks for you answer. Did as suggested. Now the numbers get even more random. E.g. when i start at 201mm sharp next number ist something with three decimals places. Isn't there a way to define how much an arrow press should make things move? In my case ex. 0.1mm?

Ok i got it: Nudge Distance. Weirdly this was set on 1mm but when moving with the arrows it didn't move 1mm. But now having set it on 0.1mm it moves accurately
