ArcGIS Pro 3.2.2; File Geodatabase
In the Calculate Field tool, fields like Shape_length are available in the Field Name parameter drop-down. However, Shape_Length is not editable and will throw an error if the user tries to do a field calculation on it.
Is there a reason why uneditable fields need to be included in that pick list? Or can they be excluded?

ERROR 160143: Field is not editable.
