Paper module display dimensions

On the paper module sometimes the dimension shows up as 11’-12" as opposed to 12’. Is this a bug or can I configure this somewhere ?

It is a bug. We have tried to fix this in the past, but apparently it was still not correct.
We have checked again, and we have found the problem in the formatting of the text, where a rounding error causes the problem.
We are fixing the code, and this fix will be in the next release version.
