I don't know if you resolved this yet but I had the same problem. And, found a fix.

I changed my left fast blinking bulb  with a good one and all worked fine.  Nice slow blink.  

        Later for no good reason I put in a different new bulb.  and  though it worked it blinked fast. 

I removed the bulb and though it should go in only one way I turned it so the little nubs went into the opposite channels. After that it works correctly, but the nice slow blinking.

So try to turn the bulb and place back in.
