On my tablet, Export to CSV allows me to add new field sets, but does not allow me to edit sets. Nor does it show a preview. Nor does the export work.
This works fine on my mobile phone.
Also, and this is strangest of all, if I use Cloud rather than Web on my tablet, in the SAME browser, that works perfectly.
Figure that one out, if you can. 
Can you show us this with screenshots?
Which tablet do you have?
Which browser app do you use?
Can you try a different browser app as a test?
Does it work on your regular computer if you own one?
I think I have isolated some aspects of the issue.
If I set folder view to Watch Year | Watch Month | Watch Date (which is my current favourite view) then the export fails. Otherwise it works.
I am still not able to Edit the “visible columns” on my Samsung galaxy tab, Android 13.
I have a similar problem with export on my Moto phone (Android 15), but there I can edit the visible columns.
On both I use the Vivaldi Browser. On the tablet I have also tried it on Chrome Browser, with the same results.
By the way, I am reporting this because it is interesting (to me). I don’t think I will ever want to use the feature, and in any case there seem to be lots of ways to get around the problem.
Edit: I’ve just tested this on my Windows computer (also using the Vivaldi Browser). Here I find that there are difficulties if “Watched” is selected as a Folder field, but otherwise everything works ok.
I’m really sorry to say, and I must be missing something, but I can’t seem to reproduce this on my side.
You said it doesn’t allow you to “edit sets” : I would like a screenshot of the place where you normally edit sets. Do you even see the “edit” button for the set?
And a screenshot where I don’t see a preview would help too.
Sorry it’s taking so long, I’m just not able to get it to.. fail. Even with your folders switched on (but those folders with year/month/date don’t apply to the export.. so I’m even more confused now haha)
First, select the folder in the normal view.
Then go into export CSV. This works instantly if Ii have Noo Folders, or a view such as Region, but does nothing if the folder selected above includes a Watched field.
The other problem onlt occurs on the tablet. I get the screen and can add a new list, but cannot edit or delete any list. Because this seems to be device specific, I’m not sure I would worry too much about it.
Got it, reproduced now and I will put it on our bug list!
