Bulk tagged topics, then moved topics into another category, but the category tag selector doesn't show tags

I’m looking at the database content with #data-explorer.

The category_tags table is kinda empty, except for two tags (id 1 and 2) from another category which has nothing to do with my issue.

My other tag “électricité” (with 2 other tags), which belongs to the category “Mécanique”, should be present here I believe.

In the category_tag_stats, there are also issues:

The categories id 33, 32 and 34 (which here wrongly link to /t/33, t/32 and /t/34 instead of categories, which seems a data explorer bug because the query output seems alright) don’t exist anymore: I deleted them after moving all their topics in another category.

For example, the category id 33 was the category where I bulk tagged all topics as “électricité”.
Then I moved all these topics to the category id 83.

So the data in these tables are wrong, despite the fact I followed recommended commands to bulk tag and move topics.

Do these commands miss something to update these tables accordingly?
