For a start, it's Covalence dust, not convalence. And we can't really know for sure why, because we can't see what you're doing wrong in your, but I'll take a guess at what you might be doing wrong. :)

You could be:

1. Stacking the cobblestone into one stack of 8 on the crafting table instead of spreading it out on all the spaces. 2. Using coal instead of charcoal (unlikely because you mentioned that you were using charcoal, but double check anyway :P). 3. Maybe try using the vanilla Minecraft crafting table, if you're using something like a Project Table or an Automatic Crafting Table. :) 4. Make sure the server you're playing on hasn't banned Covalence dust, or hasn't removed EE altogether (that would be horrible for Mages like me D:) 5. The last thing I can think of that would be the problem is that it's just bugging out... :/. All the Covalence dust and the divining rods are all very buggy when it comes to crafting them and moving them around your inventory and chests. It happens to everyone, don't worry. You'll be able to craft them at some point. Maybe just restart your client or relog (if you're on a server). :)

Good luck with that and I hope I helped! :D
