JSON Code in sharepoint trigger issue

[mmchx]

I found the issue on the JSON code in the "For selected an item." trigger that the manual input change from optional field to the required field.

I tried to export the flow, edited the JSON inside, and then updated the flow via importing the flow. It seems fine, but after turn on the flow, it turns to the required field again.

How can I fix this problem?

Hello,

I am not sure I fully understand the issue, are you referring to this button?

Yes, after I change to optional and save. It still is a required field.
