Updating MS Teams - different versions + vulnerable version showing in Defender

Hi experts,

for months... I've been struggling with understanding how MS Teams is present/installed on our company and  laptops and why I see 20 devices out of 65 total in defender marked as "Update Microsoft Teams" as the number 2 of "TOP SECURITY RECOMMENDATIONS".

It looks like the rest of the devices are just fine... but for few months... I still have 20 devices there... including mine. So lets try to focus on mine.

I am using "NEW MS Teams" version below (checking this via TEAMS > Settings)

When I check via "Add / Remove programs", I see the below:

So I guess the Microsoft Teams on the top is the NEW TEAMS that I use... The other two are not reported as vulnerable in Defender - picture will be below.

Now, this is what I see in Defender SW inventory for my laptop when I search for TEAMS:

My Questions:

1. why I can't see the version of TEAMS there that I see when checking my TEAMS > Settings?
2. the two other TEAMS (add-in and machine-wide) are not marked as vulnerable, so thats fine
3. what are the other TEAMS that are displayed in DEFENDER SW inventory for my laptop?
4. and the most important one - HOW DO I PATCH the vulnerable ones? If I do not seem to have them installed?

I am so confused by this.... and it is really frustrating as it affect negatively the Vulnerability Score that is one of our key indicator for checking our overall security 😕

thanks for any advice
