Customize Form Error - Project Document Type

Getting an Error as below while modifying the Fields in the Project Form.

Though after reading the manual, it suggest to change some of the Field in to Text or restrict the Length Limit , but even to try the above option, we are getting the same error. We have tried to convert some of the fields from Data to Text, but the same error we are getting, even we at the modification to convert the fields in to text itself we are getting the error. It is not allowing to modify the Input Field Type

Can anyone help on this, as our we are on hold and not able to add more customs field

@NCP , Can you assist on this.

You should delete the custom field.
Then reload your system.
And again add the field and check it.

Maybe solve your issue.

Thank You!

Thanks a lot. Appreciate
