Philippines year line deletion [решено]

For this:
https://en.numista.com/catalogue/note205311.html

I've been told by a member that " Mr. Amando Tetangco Jr. served as the Governor of the BSP from July 4, 2005 to July 3, 2017. So there is no such banknote dated 2018 with his signature." After a quick search I found out he is right.

So the year line 2018 Signatures: Duterte & Tetangco should be deleted. My question is what to do with the members who claim they have it in their collection?

I moved those members to the Undetermined year-line and deleted the erroneous one.
