I have mis-named a field slug in the custom field group here: hidden link

the field is "ID (IN)" and the slug is "fmc-iid-in" I want to rename it to "fmc-id-in" but i get the warning: "Warning: field slug already used"

however, when i try to add existing fields, that does not appear. I also have looked through the other field groups and there is no field existing with that slug.

why can't I use this slug? how can i fix this incorrect warning?

Hello,

Please check it in your website:
hidden link

There does exist a custom field using same slug "fmc-id-in", the field name is "ID (In)", so it is expected result that you get the warning meesage:
"Warning: field slug already used"

In your case, you can try these:
1) Edit the field group
hidden link
Find and remove the custom field "IID (IN)"

click "Add New Field" button-> Choose from previously created fields, see my screenshot, find and select the exist field "ID (In)", and test again
