Hi @Dirisenapu9,
first I would suggest to test this in an "Incognito Window" (close all Incognito Tabs before).
In the QA link, if necessary, also specify that all other activities should be displayed only default content.
Alternatively, check if e.g. the at.js is included twice or loaded twice (this can be checked in the developer tools under Network if the library is loaded twice).
Maybe this already helps you?
