No, no. Not to worry. It is "suggested" that the "outside foil" be 
connected to ground since this can improve the shielding and 
bypassing, and reduce the pick-up of noise, etc., but NOT doing it will 
most certainly NOT upset the IF circuit!

There was an article in ER magazine some time ago concerning the 
building of a device that would help you figure out which lead is 
connected to the "outside foil" in those caps on which it is not marked, 
but in this case, I don't think it will materially effect the receiver.

Don't worry about it.
