See this Comm Center post by Ton van Vonderen (part of a thread containing several unrelated issues). There are several issues in here, but one is that the scheduled periodic autofocus feature is n/a on a system with comma decimal point. Maybe add | as a possible alternate separator.
This was a bit of a nightmare since the numbers are stored as numeric strings with delimiters. One rabbit trail identified and backed out of. Now converts the old ',' separated to the new '|' separated automatically.
