I have never see anything like that happen. It almost looks to me like a solvent was spilled on the bag OR it sat in a hot trunk too long.

Nah, I keep my clubs/bag indoors, never leave it in the trunk (Hawaii). Strange that it is only happening on one side of the bag. The logo on the other side is fine.

How long have your had the bag? If you have not had it over a year, you should take it back to the store where you purchased it so they can get in touch with Titleist for a return authorization. You might need your receipt from the store you purchased it from. If this fails, the Titleist Golf Clubs Warranty and Repairs Department may be reached at 800-742-7609.

Unfortunately, all of us on here are loyalist and consumers like yourself and cannot resolve you issue, only advise you. Hopefully this information can help you. Below is Titleist warranty information.
