I am having problems with watermarks in LR, when I am finished editing a watermark and got back to the export dialogue box, the watermark is empty, I then have to select the watermark i was just editing to use it. This has just started happening after an update so I can only assume it's a bug. Also when mobile syncing the sync stops working and won't upload any more photos. any help is much appreciated . LR version is 2015.4.
