Minor BUG report when adding sign "+" in the name script to a TEST

Hi,

usingLoadRunner EnterpriseCE 24.1.

Menu test Management

When adding script to a test, it allows me to add  sign '+' in it  

NO+_inScriptName

but when I want to execute the test, I have this error =>

Timeslot cannot be reserved. The loadtest inside the reservation has become invalid

Timeslot_cannot_be_reserved

Finally, I change sign '+' with '_' in the script name and the test goes on without errors.
