Why does Google Analytics connect multiple times?

Question

Google Analytics

Hi everybody!
There are several sites on Wordpress.
All use Google Analytics connected through the Google tag manager.
On some sites it is simply connected, on some sites sending events is configured.
The problem is that all sites connect //www.google-analytics.com/analytics.js several times. The maximum was, as much as 10 connections.
At the same time, all data is displayed correctly in Google Analytics.
Example:
I sin on Google Tag Manager, because one of the sites does not have it and Google Analytics is connected directly. There is no duplication on this site.
Google does not give any adequate information on the problem.
Tell me, please, where to dig, what to watch, maybe someone came across? What is the danger of such a multiple connection?
ps I can't show the sites themselves, everything is under the NDA.

Answer 1

On https://r-specteh.ru/ , the analytics is also connected via the tag manager. This is how it looks in the manager skrinshoter.ru/p/111017/X1GYMv and this is how it looks in the page code skrinshoter.ru/p/111017/Zx2fx1
It would be interesting to look at your tag configurations - maybe then it will become clear where this duplication comes from.

Answer 2

GTM doesn't include any extra code at all on the page other than what you put in yourself. Check the Wordpress settings, maybe there are additional codes somewhere in the settings. Even more reliable - look at the source of the pages themselves. Maybe GA is on several pages and when rendering it throws everything into one place on the page.
