In the PRV when using drum maps with the Display Pitch Names option the column is not wide enough so the last of the digits is cut off for some notes, as the width of the digits varies. For example G#0 is cutoff, but F#0 is not. Seems like a simple fix to widen the column.
It's been this way for a long time, so not a new issue.

Slightly confused if you are talking about the left hand pane in the RPV it is resizeable?  What version of software also?

I'm using Sonar Platinum. The issue has been there as long as drum maps have existed. I've been a Sonar user since version 2.0. Yes the left hand pane. It is resizable, but there are five columns in that pane. Resizing it only affects the size of the first column.The relevant column here is the second and third one.
