Issue Summary

When the option Simple Create as Default is turned on, some users are unable to create work items due to the following error:

"errorMessages": [],
"errors": {
"customfield_xxxx": "Field 'customfield_xxxx' cannot be set. It is not on the appropriate screen, or unknown."

However, the fields are not required or anything, seems to be a cache issue. Even when you try another browser/network, the issue persists.

1. Have the option Simple create as default enabled
2. Try to create a work item. 

Expected Results

Actual Results

"errorMessages": [],
"errors": {
"customfield_xxxx": "Field 'customfield_xxxx' cannot be set. It is not on the appropriate screen, or unknown."

Workaround
