Google Analytics doesn't split data view into individual domains

Question

I have multiple domains (like domainA.com, domainB.com, etc.). They are unrelated to each other. Each domain has its own tracking number.

I have created a single GA account named "tws".

Under "tws->Properties and Apps", I see these different domains.

When I now click a domain in the list "Properties and Apps", the right side "Data View" shows "All Website Data".

When I click "All Website Data", it doesn't show me the data of this website.

I can tell because no matter which domain I click, the data always stays the same. Even when I click a domain which shouldn't have any visitors, it shows me the visitors of some other domain.

Does anybody see which mistake I made?

Thank you.

Here is an excerpt of GTM:

Now that I made the suggested changes in GTM, Chrome's tag analyzer shows this:

Answer 1

I looked at one of your domain (seen in the previous image). And as you can see in the images below, you're sending hit analytics to all your properties... so I suggest you to review the configuration of your GTM and send hits to the right domain.

Solutions:

PREFERRED: use a lookup table to send hits to correct Property based domain.

Or:

use a separate GTM for each domain.

Or:

use separate Analytics tag in the same GTM for each domain (not preferred but working).
