Still struggling with total of pages of report

On Report PDF header I added a field with “Current Page” and “Total page” .
Current page works and
Total page absolutly not .
Anyone of you had this problem to fix in past ?

It’s a SC ready to use variable I suppose.

After many tests the problem is a bug. The workaround is to set Text font to “Times”. The SC said that they will fix bug on next version. Bye
