[#5324] - REPORT_MAX_COUNT doesn't work in JS 3.7.1 and 4.1

Importing my reports from JS 3.5 to JS 3.7.1 or 4.1 I think to have found a bug on instantiation of the built-in parameter REPORT_MAX_COUNT.
Im my reports a user can choice REPORT_MAX_COUNT number from a "Single Select List of Values".
This works always in JS 3.5, but in JS 3.7.1 or 4.1 doesn't work if in the same form "Cascading Input Controls" are present.
If I remove them report runs, but links inside it that send REPORT_MAX_COUNT to other reports don't work.
See attacched images to understand the two errors.
