Why are my hashtags working on one account but not are working on my other account on Instagram?

[colossalframe544]

I have two pages on instagram, two days ago the tags stopped working on one of my pages. I have a personal account and one where I share some photography I've taken on some of my hiking trips. I used the 'InstaTag' app, which give me the top 30 tags. I used the tags on my page with my trips and realized I was not getting as many likes as usual. I checked one of the tags and noticed my picture was not in the page with the tag. I copied the same tags on my personal account and used the same exact tags on the picture, which all worked.
I do not use any tags like #iphone #boobs or stuff like that. All the tags work and have pictures on them. No tag shows as '0 pictures' and get my picture from my personal account tagged on the page.

Please HELP ME!!! What can be causing this? I'm updated with the current release on both phone and Instagram/

Some hash tags like boob and IPhone Don't work, it's just how it is.
