iTunes update duplicated?

[DaveWT]

On Oct 28, the App store told me there was an update to iTunes so I installed it and got 12.5.2
Yesterday (Nov. 1) the App store told me there was an update to iTunes so I installed it and got 12.5.3
Today the App store told me there was an update to iTunes and offered me 12.5.3 again. I let it install just in case it was slightly changed.



Has anyone else had this experience?

Just an update here...

The "12.5.3" update installed on Nov. 1 was actually 12.5.3.16 (seen under "About iTunes")
The "12.5.3" update installed on Nov. 2 was actually 12.5.3.17

Pity there wasn't more info provided by the App store.
