More 5E on Roll20 Questions

I'm looking at the sheets for my characters in my 5e game, Using the OGL sheets and the Compendium.  When you expand their weapons it shows the attack roll and damage, both of which are checked, then there are two more line items that are unchecked by default for another damage line, and then a saving through for STR vs Spell. I'm not sure where these are coming from and why they're on every weapon. Can anyone clarify what's going on there? Also when I click the "i" tab so I can look at items quite a bit of it comes from the SRD and not the PHB. I would have expected PHB versions to universally override SRD versions. 

Can't comment on the compendium issue, but for the attack repeating sections. They simply have all the fields that you might need for an attack. You enable/disable them by checking them.

Jeremy - the PHB items SHOULD be the first ones you see, but if there's a naming difference (Acid Arrow vs. Melf's Acid Arrow), the one that is dragged is what's populated. 

Hmm, for stuff that is identical in the PHB and SRD, I think I was looking at Handaxe in items, what happens there? Does the PHB just not implement those at all and only the SRD content is available?
