Resetting Parcel Fabric Label Displays

[wwnde]

I am trying Parcel Fabric for the first time. It has gone in well except the directions and distances are only displaying at very low scales.

At 1:50000 which is a normal view on my screen, the dimensions do not appear. 

I have re-tweaked the  expression in arcade window as highlighted below but that does not quite help. 

Tweak to change spacing 

and

to change text size

If someone knows what needs to be done shall be highly appreciated?

Lastly, split of the record does not directly update the affiliated subtypes. Is there a more direct way than split parent method?

Cheers
