BUG: Eldritch Blast compendium item does not drag over to spell sheet

I noticed that the spell Eldritch Blast does not drag over to the OGL character sheet like the spell Fire Bolt or Light does. When I click on the down arrow to get the short description of the spell it tells me what it does, but if I actually click on the compendium link, it goes to a link that has a section for logging in, as well as a section to purchase the players handbook. Eldritch Blast is an SRD spell.

You will only have access to spells from Players Handbook if creator of game owns the Roll20 version and is sharing it (I believe this way works).  Otherwise you are restricted to what WotC provided in OGL-SRD.  I believe Eldritch Blast was not included in the original OGL-SRD when Roll20 set up Compendium.

Eldritch blast was added later, but is now included in the SRD. Now that Roll20 has the Player's Handbook available for sale, it may be that some old configuration data is still marking that spell as non-SRD, and directing you to the purchase page.
