Change the bulbs 1 at a time & see if it makes any difference as you could have a dodgy bulb that only starts to work properly after a second or two.
The relay relies on the resistance of the bulbs to operate correctly, if a bulb is out then the other one flashes fast.
I don't think that the side repeater bulb being out makes them flash fast.
