I cannot load logic plugins presets with logic pro x 10.2.0

HI.

I´m working now with the logic plugin Ringshifter. I´ve created a new preset and then I saved it. When I try to load any preset with the plugin i cannot load (all the saved presets appear in light gray and can not be loaded). I tried with anoter plugin (ensemble) and i get the same results: I cannot load the saved presets. With Logic pro X 10.1.1 all is working as expected an I can load the preset without problem. So i think is a logic 10.2 bug. Has anyone else had this same problem?

My Os is Yosemite 10.10.5
