Dropping Player's Handbook icons onto a map don't conform to a 5 ft icon space, as they should, (or any other icons)

Essentially, if I open a folder full of Icons by clicking on the title of that folder, which then gives me the popup to select multiple icons) and then try to drag those icons onto a map, they are majorly oversized, and don't subscribe to the grid block that I'm dropping them into.  If I drag them directly from the art sidebar, they will.  But if I actually open the folder, select, say, all of them, and then drag them onto a map, they are approximately 3 times larger than they should be.  Is there something I'm doing wrong, or is there a workaround?

Correction, I believe the correct term is "tokens", not "icons".

You have the opposite problem to almost everyone else! Dragging tokens from Folder view uses the dimensions in the artwork, dragging from the Art Library uses a 1 unit square on the Object layer and a 3 unit square on the Map layer. 

It is a temporary problem that Roll20 has announced will be fixed soon. New functionality was given to Marketplace art drags which allows them to be dragged in at intended size. It has broken the regular drag behavior in the meantime. You can get the old behavior by dragging from Folder view for now.

I think maybe I didn't explain this properly.  What I mean is, when I select tokens from the Folder View, they drop on the map at 3 times the size they should.  I actually want the tokens in Folder View to conform to the grid square.  My reason for doing this is to make a landing page of tokens for my players to choose from when they make characters.  Once they select said token, I want to copy and paste that token into the next adventure map, and I want them to be appropriately sized.  Basically, I WANT to use folder view to select the tokens, but they drop in oversized.

Yes, I understood that, and I suspect the tokens are oversized, because most tokens are created oversize and scaled down to 1 unit. IIRC this is the advice from Roll20 on making good tokens. So you're getting tokens at their actual size, not at 1 unit, because you're dragging from Folder View. It's Catch 22! 

Hi Rastane Darklore, If they are dragging in at 3x size, it sounds like you are dragging to the map layer, where the default is 3x3. Currently, if you drag from the journal to the VTT on the token layer, it should auto resize to 1x1. Dragging from the Folder View to the map layer or the token layer, they will come in at the proper aspect ratio, but either in a 1:1 pixel size for smaller graphics, or with the longest dimension at 200 pixels (again, at proper aspect ratio). (Just to clear up any ambiguity, when you say "Folder View" you are not referring to the Art Library tab? — They are different things.)
