Issue with stamping

Hello everyone,

I've encountered an issue with the stamping process in the layout. 

In the standard configuration, the detail linked to the title block table is correctly identified and stamped with the number 36. However, in the OPEN FRAME configuration, the detail is not recognized and therefore not stamped.

Has anyone experienced this issue, or could someone suggest a possible solution?

Thanks in advance!
 

 

 

Open frame configuration: stamping not recognized 

Standard configuration (closed configuration): correctly stamped
