Pathfinder first edition compendium with paizo connect

So a year back I got all the pathfinder first edition books on Paizo and I found out that I could connect my roll20 and Paizo account. But I checked in the compendium but I can only seem to find core rule book things. Even though I have all the bestiaries and everything related to pathfinder first edition. Does this mean that all the books haven't been put into the compendium yet or is it bugged or something? Thank you for any help!

The only thing in the compendium for Pathfinder one that requires money is the Bestiary 1.  You get the pdf from Paizo for free if you buy it here, or you get a reduced price here if you already bought the pdf from Paizo.  Having that will mean that monsters from that book will have their tokens and everything set when you drag them from the compendium.  You also get the tokens separately as an addition to your art library. Basically, when you bought stuff from Paizo, you got the pdf.  If you want the Bestiary here, you still have to pay for the compendium integration on this platform. 

That.... Is horrible. Like sure it is more along the lines of paying for convenience but still, I have already bought the books. I just don't want to randomly send around gbs of PDFs to my players.

You are paying for integration into the platform that isn't all done by paizo.  You can copy paste anything you need from the pdfs.You can build a base game and copy that any time you start something new.  That way, you can things set up as you wish.  Yes, it is convenience, but the convenience is the result of a lot of hours of coding. Not sure there is much to complain about.  Pathfinder 1 has the most compendium content available for free of any game on here, I think.  Integration into the platform, sheets that accept compendium drops... those things aren't quick and easy.  If you don't think it is worth paying people to do that stuff, then don't.  Since Paizo is now focused on 2nd Edition, I doubt more content for 1E will be integrated.  Time will tell, though.
