Can't merge two pages with different roman numerals

I originally posted this thread to raise a problem, although I wound up figuring out the solution on my own.

Still, I think that the staff may want to take note of this.

I was advising a person on how to merge two name pages for himself with different roman numerals. But I forgot to use "Name Merge" and instead tried to do that with a "Name Correction". And, in doing so, I wound up getting "red" error messages that I couldn't resolve, such as in the following example:

May I suggest that some additional information be added to a warning such as this, along the following lines? "If you are trying to merge two existing name pages, please submit a Name Merge instead of a Name Correction."
