UPDATE:

The blocks do actually cross over but they are just not showing in in the paper space view port for some reason on all the layouts of the sheet set. They show in Model space but not Paper space. It is just a few blocks though, ones i imported ready from online sources do not have this issue and a couple i have made from scratch also are visible in paper space.

Add on to that that i just noticed that all dimensions are also not visible from the paper space view port ! note i add my annotations in model space. I checked visibility, plotting and new VP freeze of course and they are all set to have the blocks and dimensions be visible from the view port. 

Support you guys please, this is a mess you can imagine plotting sheets with no dimensions and doors and windows !
