Page won't show up under tag

Help!
I have just one page that isn’t showing up under a tag. Every other page with the same tag is showing in the “directory” under “women’s fashion” except this one pgae which only shows up under my “directory” tab if I have it tagged with “jewellery & watch makers”. It needs to be under “women’s fashion”.
When I compare it to the other pages everything is exactly the same and I’m really not sure what else to do now. I’ve deleted the post and created a whole new post with the “wf” tag but to no avail. Please advise, I’m still quite new to WordPress!
