I have run into this Time card error after upgrading to version 15.3 +.
On pressing Calc Daily
“ Employee has the following errors:
Time card rule errors:
Multiple matches of OverHoursPerDay found only one allowed.”

We have not changed or altered the time card rules as existed before the upgrade and even currently the time card rules have only a single Overtime Rule. In fact it is just not possible to make two rules even if you want to by design of the software.

Any and every help would be much appreciated as we use Open dental not only for attendance but totally for calculation of salary as well.
Thanking in anticipation
