I have many presets in about 20 separate preset folders. VSCO, Mastin, personal ones, etc... Let's say I choose a preset in a folder about halfway down the stack. Click. Applied. - Now I go back to the Library Module. I then switch BACK to the Develop Module and look for my presets ABOVE the one I just applied. GONE. To this, there's a big empty space BELOW the bottom preset folder that coincides with the amount of real estate the missing presets should take up. I know, strange, right?
Has anybody else found this problem too? It resolves itself once I restart LR. More to that, it doesn't happen every time, but about 75% of the time. It only started happening after the latest update.
Windows 10, LR 2015.5.
