Now everything is clear...
You have a few sheets:
and probably you expect to send filled forms to that named results right?
ODK Collect doesn't know which sheet you want to fill so it always tries to send data to the first one, in this case, it's survey which contains other data and can't be used.
A simple solution is to move the results sheet before survey (I did that and was able to send data).
Probably you thought that the link you shared is to that results sheet but that's not true it's a link to an entire spreadsheet and as I said the sheet you want to fill must be in the first place.
