HTC One (Rooted) Wont system Update (keeps asking to update after the update)

Hello,

So I been receiving a message on my HTC One M8 for a week now that there is a new Firmware update available (System Software update 4.20.631.3) and it downloads fine... I select Install... the phone reboots I see the installation process going on... then the phone comes back into the main menu like normal....... and it ask again that there is a new update if I want to install it (the same update)... every time I keep reinstalling the update, after the installation It'll ask to install it again. If I cancel the update... it'll ask me again later which is really starting to piss me off.

Phone: HTC One M8 (Rooted)
Android Version: 5.0.1
HTC Sense Version: 6.0
Software number: 4.20.631.2

Thanks for the help
