When I go to edit profile information trying to change only my custom member title, it says ''You entered too much data for the field 'Our Story', please go back and check the input'', but I didn't change the our story, just the custom member title. What can I do?

I had reduced the maximum length however I have again made it larger. I hope it is good enough now.

I transfered my complete K1 timeline to my timeline page. My Profile Information was too big anyway. Thank you very much.
