Dashboard layout lost after re-login

Hi,

Every time I re-login to grafana I lose my custom dashboard layout. No matter how many times I save it, it does not keep the changes.

I tried to edit the Json Model and save - the Json Model does not get saved after I press the save button.

Please, help me here! it is quite a pain to reorganize +20 charts every time. Btw, I am using Grafana v6.7.2

Thanks a lot,

marcelo
