Can't customise dates in reports

Hello all,

I am generating standard reports that are already available in the system.
The reports show me all items since the beginning of installation, the date specification bar on the top does not seem to work. I tried changing it to Today, Yesterday, …etc. I tried manually specifying the date. However, it is always showing me everything since the installation of the system more than a year ago.

Also, is there any way to make the default filtering time for this month only. From what I see in the standard reports dates are not specified and they seem like a built-in feature.

I appreciate your assistance

Did you close your work periods on a regular basis?
