Value not found in options in parameter

[rafaldo]

I want to Create Record by API and one field "Multiple choice" throw error.

I want to add "Other" value and I get "Value not found in options in parameter"

And when I try add this option I get error, even if it's one of valid option 

In other cases like "SP z.o.o.", "SP akcyjna", "SP komandytowa", it work well.
