Hmm I have to be honest the Calendar module in farmOS v1 never got much love and attention - this could be a bug.
And full disclosure, there is no calendar in farmOS v2 anymore. We’ve pretty much decided that farmOS shouldn’t reinvent that wheel. Instead, we’d like to make it possible to import farmOS logs into external calendar applications (via standard formats like iCal). There is some discussion about that here: Re Google Calendar
So unfortunately, this is probably a “won’t fix” situation for v1 @texasecofarms - unless you or someone else wants to debug it and contribute a patch.
