We had a similar issue. Our dining table was hitting the the island when fully retracted, just a kiss, but it was enough to leave wear marks on both the table and the island cabinet, not the sink top. I was going to move the island a bit, but then we wouldn’t be able to open the refrigerator door with the slides in. I opted to remove the table top and cut 1/2 inch off the wall side of the table top (our table is wall mounted) then shifted everything back 1/2 inch and now have 1/4 inch of clearance.
