Ticket time tracking doesn't stop

Hi there,

For a couple of days, I am facing a problem with the ticket time tracking functionality. I have started time tracking on a specific ticket but I don't know why I cannot stop the tracking.
I click on the " Stop work " button and a pop-in displays the message " Work finished " but the work time input boxes don't update and the time tracking doesn't stop on the ticket.
See attached screenshots

Could you please tell me how to proceed to stop the tracking on the ticket ?
Thanks for your feedback.

Regards,

Olivier
