Hi @stephan_diedrich, @rweinber (Welcome to the Community!),
Could you share with us the screenshot of the issue that you are having. This issue was reported earlier and was fixed by our developers. Maybe we could share your screenshot with them again (so that they would have a look at the issue). Would also appreciate if you could let us know the server (OCHA or HHI) you are having problem in.
In the meantime @rweinber, you could download your xlsform and save it somewhere so that you could re-use it again (which will not hamper even if you close your browser). Maybe you could upload the xlsform and try it again if it works for you or not. The way to download your xlsform has been discussed here:
