Duplicate Updates for Office 2013

Hello,
after several tries and re-tries to install some Office 2013 updates, it was giving me errors or download problems, now my win10 seems to be happy with its updates.

My problem NOW is that i have multiple and duplicate (x3 or x5) entries in the installed entries in the Installed Updates List: see screenshots



In the registry I found those duplicates in these keys location, an example for all:
Security Update for Microsoft Excel 2013 (KB3085502) 64-Bit Edition DUPLICATES 5 times.

As you can see what changes is the Product ID while the PatchID is the same.

Should I clean duplicates entries?
Will it affect my system performance?
I'm afraid it will defrag and bloat the registry.

Thanks for your help

Is this behaviour normal?

Thanks

I would like to have other people opinion, because I'm feeling that is a normal behaviour; I mean that updates patches applies to different office products: word, excel, onenote, etc...
so for some reason it register the update entry 2 or 3 or 4 times.

Anybody can confirm this?

Thanks
