ARCHICAD is adding spaces to the end of my Zone name

[4hotshoes]

It must be a bug. I have the zone stamp set to fixed width, which may be doing it, but why? Should not. I am using Autofill for my drawing label, which references the Zone name and then more text. It keeps adding spaces and pushes the following text back. Has anybody else experienced this? Is it a setting or fixable?

I delete the spaces, change the name without spaces, but AC 23 and 22 adds them back in after I place the zone.
