Taskwarrior

OK here is one that is confusing. It may not be an issue but it is an inconsistency. To repeat this please do the following:

first run "task rc.calendar.holidays=none cal"
then run "task rc.calendar.holidays=sparse cal"
then run "task rc.calendar.holidays=full cal"

When the "full" is run it appears that a "clear" command is run but not for the other to settings. is that how it is suppose to work? should a "clear" be run for all "cal" commands or should it never clear the screen. Just something I notice.

Thanks again,
SoBBie

PS. I apologize for all the questions. I do not want to be a bother so please let me know. As I said I just started using this and I am trying to find all the "little" things about it that I can.
