Garry,
couldn't spot mine, but would not look at yours neither
But let's try to pretend that we are strictly professional, so...
Linda, check the picture below and see if the gap in your HT is larger than this one... I think that 1/3 inch is quite OK.
Moreover, maybe the larger than expected gap is due to the very fact that your HT just underwent renovation and if you fitted new seals, they need time to settle.
