Skipped base backups

I have Ghost 15 configured to run a new base backup once a month, and incremental backups daily. Every once in a while, it will miss a scheduled base backup. If I tell it to run the missed backup, I don't get a new base, I end up with another incremental. These incrementals will continue back on schedule, and the only way for me to get a new base is to delete everything and start from scratch.  A base backup won't run automatically until the beginning of the next month. 

 

This seems like a bug to me.  Missed base backups should be run as base backups, not incrementals.

 

Anybody have a fix or workaround?
