Can´t save view

Can´t save view

Hi Zoho

I have a problem with saving a view. I wish to remove "entre" + "billetpris" from: 
https://creator.zoho.com/runehagel/events-cafezusammen/#Page:Informationer_til_kommunikation

I however get the following error when trying: 

"FAILURE:Error occured while saving the view. 
Kindly refresh the page and try again later". 

I have read in other topics on this forum, that this should be a problem on the serverside. Can you please help me ? 

Regards
Rune
