I came over from amy-goodrich's post to see the tags but still see 5 tags here. To drop one tag, you have to Edit this post and pick one to sacrifice and delete that. Then, finally click [Update Post]. Review and make sure there should be only 4 tags. If doesn't see to work, then try to clear the cache in the browser and reload.

If I look at a resteem post from you:

There's 4 tags and I'm able to see it in:

So, it works :-)
