Thanks for the input everyone. The tarp is only about a year old and has only been out in the rain maybe 4 or 5 times. So, my worry was quality control as I don't think its so old or heavily used to be a wear issue. And I wasn't sure if seam sealer would address the problem. Since it is happening on two different seams I thought maybe there's a bigger problem that I'd find out about on a trail in the middle of a storm. I'll contact them and see what they say.
