Hello,
Thank you for bringing this to our attention, and please accept our apologies for the inconvenience.
I have checked the article link you shared on my end, and I am not seeing the Popular Tags module displayed on the right-hand side. From our testing, it appears to be hidden correctly. For reference, please see this screenshot:

This behavior is a bit unexpected, so it may be related to cached content. Could you please clear your browser cache (and any site/server cache if enabled) and then check again?
If the module is still visible after clearing the cache, please let us know and we will be happy to investigate further.
Thank you for your patience and cooperation.
Best regards
