I could have answered my own question regarding the new subscription method, I have 7 full pages (50 items) and page 8 which has 3 items.

For some reason Watch Later, Liked, Videos and History are blank and/or have been populated by most recent plugin viewed videos, On youtube.com everything works fine and has been updated properly too. Cache problem or bug?

Try to delete the cache of the addon. But I think it had to do with your account and not the Addon. YouTube is some kind of a mystery.

Yeah its an account problem, I'm getting the subscription info from my "main" account but the the rest of the data is from the Google + page which is actually what I use, (I think) which only has 1 subscription and none of the other data. Something like that :lol
