Time Group Reporting - issue with deviation days that are days off

Hello 

Wondering if anyone ran into similar situation. Our managers use “Time Group Reporting” to create deviation days for the bulk of employees (whole shift for example) or for longer periods of times. Using “Employee Deviation Days” for situations like this is very time consuming and inefficient. The problem we get is when we register a deviation day which is a day off (non-working day). When we try to authorize such day (which has no attendance or other clockings) we get and error that: “The Time Card already exists”. After short investigation I find out that “Time Group Reporting” creates a empty time card  in database for any day that has been updated as deviation day, hence this prevent day from being authorized. “Employee Deviation Days” while does exact same function does not have this issue (empty time card is not created in DB). Actually one of the fixes is to update “Deviation Day Type” in time card which removes the empty time card from db and allows us to authorize the day. 

Have anybody ran in to same issue and found or know how to fix this?
