Do I run both Internet Security and Total Security?

All:

TS - Bitdefender Total Security

IS - Bitdefender Internet Security

I checked my Subscription --> Services when I got an expired notification on my desktop. I found I have both IS and TS services(which are NOT expired despite what the desktop pop-up says - I'll look into that later).

Some months ago I called Bitdefender Support because I wished to add Android phone protection and purchased TS. So I now currently show:

IS - 0 of 3 protected.

TS 3 of 5 protected.

Question: Do run both IS and TS on my Windows PCs? I see they are distinct packages, but this just seems very un-streamlined. Particularly when many posts indicate TS as an upgrade from IS. If memory serves, BD Support also made that claim.

Thanks!
