apple watch strap

i recently bought an apple watch and for the first few days of using it i didnt notice but yesterday i noticed that the straps are wobbly, one more than the other. so i took the straps of and re attached them to make sure i heard a click which i did so i left it and put my watch on only today i noticed that its still doing the same thing so i repeated the same thing and heard the click but they still wobbled, so i took both straps off and tried the M/L strap on both sides of the watch and it doesnt seem to wobble like the others do. could it be the watch or just the strap?

let me just say the straps dont slide out they just wobble.
