Why does andoid want to update to the same version

[Android Central Question]

Android keeps telling me it wants to update from version 8.0.0 to 8.0.0
on phone Pixel XL
This is the third time the update has appeared (second repeat).

is this normal? A tweek to a security update (where i would expect version number to increase), or an actual unnecessary repeat of the exact same update?

If it's not suppose to happen, is there a fix?

Security updates don't change OS version.
