I also can't view the images, but we had some issues with a couple of soft close slides when our kitchen cabinets were new last year. I discovered that the closing linkage at the rear of the slides where the piston/spring is had come disconnected somehow. I also had issues with the trash/recycle drawer slides not closing properly. This one was due to some mounting screws backing out and causing misalignment enough to bind the closing mechanism. I also lubricated the slides with a silicone spray. No issues since.
I've gone out to find myself. If I return before I get back, have me wait for me.
