tableIdDigitCount=0 not working

I have my persistence running on a Synology NAS.
In the jdbc.cfg I’ve defined

tableUseRealItemNames=true
tableIdDigitCount=0

When renaming my tables they do get renamed, however I still have a suffix so my tables are named: itemname01 etc. I would expect them to be gone when setting DigitCount=0

Anybody an idea??
