Steps To reproduce

Ticket template: Time to resolve- required
Create ticket with SLA/OLA plan selected.

Your GLPI setup information

yesturday upgraded from 10.0.10 to 10.0.12

Anything else?

This is pretty important bug, as support can't create tickets as expected.
Workaround- Turn off mandatory field TTR.
When TTR is empty, ticket is created as expected.
