I noticed the comma as decimal separator but thought you wouldn't have made it through two years with that as an issue. Is it possible to temporarily switch your PC to the dot as decimal separator to see if that cures the problem?

Yes, changing decimal separator type in Windows' regional options worked like a charm.
All hail Steve, Great Admiralissimo !
