Has anybody had the problem of swelling or bubbles at the seam? Right in the middle of the dining area where we installed Kronotex Clic2Clic about two weeks ago, a few "bubbles" have appeared right at a seam. There are three swells on a seam going down the length of a plank, each about an inch long and taking about 1/2 inch of plank on either side of the seam. The tenants just moved in a week ago. Could they have dropped some liquid to cause this or is this a manufacturers defect?
Any info appreciated.
Thanks,
Janine
