Hi,
Thanks for the report. We will perform some tests.
The code under "save & close" is the same than the "save", the "save & close" call the save and then redirect the the dashboard (instead of staying on the same page). So I'm not sure I will be able to reproduce the problem.
But I'll investigate in order to find what can be the source of this trouble.
Kind regards,
