Hi Thomas,
I’m sure this reply is way too late, but I’ve had that problem myself a couple of times. Just recently I had some flow tabs go missing from the editor, but still working as intended. There appears to be a bug with the editor, causing a formatting error in the flows_*.json file under certain circumstances. It happend for me when I deleted a number of disabled tabs which I was using to store code examples. After I deleted the tabs and deployed, I had missing tabs that were previously OK. I have also had all tabs come back blank after a deployment. I copied the flows_openHABianPi.json file and imported into node-red (on Windows) and found that some flows that were previously in seperate tabs, were now on top of each other in the same tab. I assume this is due to some corruption in the flows_openHABianPi.json file, so it can be fixed by going over the flows_openHABianPi.json file and manually fixing formatting problems, or using the editor to copy/paste as required. Suffice to say its a pain if you have a lot of code!
Note I am an electronics guy, not a linux guru, so if someone has a better way of doing this please feel free to comment. I couldnt find a straight answer to the question of how exactly to copy the flows_openHABianPi.json file (on openhabian) and it took me ages to work this out.
