I'm getting this status message:
The Following Option Values contain value fields that do not match the Data Type of the Option Group
It references an Option Group and a option value of "No". The actual option value is 0 (zero) and the label is "No". The table looks ok. The field is defined as an int(11) and all of the records have values of 0, 1, 2, or Null. This option group is shared by another custom field, but no warning about that one. I haven't had any issues entering or displaying data.
