Splitting struct pins calls override warning - does not remove warning when saved as warning states

Splitting struct pins calls override warning after compiling a blueprint. The warning states that it will be removed once the asset is saved, however upon saving the asset does not disappear.

1. Open Editor (any project)
2. Create new Struct>Add several variables to struct (any variables)
3. Open any blueprint
4. Add Custom Event
5. Add Input pin to Custom Event
6. Set it to type <user created struct>
7. Rmb struct pin>Split Pin
8. Compile blueprint
9. Save blueprint

Results

Warning appears:

Warning Override pins have been removed from  123 , please verify the Blueprint works as expected! See tooltips for enabling pin visibility for more details. This warning will go away after you resave the asset!

Upon saving, warning does not go away as the warning says it will.

Expected

Blueprint compiles, no warning appears. If warning does appear, it is removed after saving the blueprint as instructed.
