ABAP program - number of old versions

Hello,

recently I have modified an Y* program several times. However, when I go Utilities/Versions/Version Management,

I see only the last 6 versions?

I remember clearly that there were more.

Is that standard behaviour - SAP saves only the last 6 versions? Can I adjust it somehow?

I could not find any information on the internet, please advise 😊
