Is it true you cannot add a duplicate personal report name per App?

Asking for a friend, 

A coworker just pointed out he is getting a duplicate report name error from Quickbase when he tries to name a personal report the same name as a report in a different table.

For example there are  'temp' reports in every table in the App and never a problem.

He has a 'temp' personal report in one table. When he tries to add a 'temp' personal report in a different table, he gets a duplicate report name error.

Is this known or does he need to clear his cache again?
