Can't fix name because of uppercase letters

Trying to update my name, which was submitted as "Apple, K.K." by someone else. When I try to update to remove the extra periods, it gives me the following errors about capitalization:

'Apple, KK' ends with an uppercase letter and is therefore invalid.
'Apple, KK' contains combinations of characters which are not permitted in IMDb names.

Any idea about how I can fix this?

Thanks!
