Redmine

Hello,

In our redmine we have an issue with adding entries to the time tracking. As we use it in german language I can not give you the exact names. In a ticket and in time tracking directly, a double click on send/save results in double entries. Is that a known issue? How can this be fixed?
I added screenshots of the form and the result when save ist double clicked.

And as the first two screenshots are out of a plugin I added two from adding time in a ticket.

Please let me know in case you need more information!
