Camera Raw and vanished Presets Problem

Bridge Version: 14. 0.2. 191

In 'Create Preset' Dialog, I created a Group and have created a few of presets under that group in ACR. This newely created preset group was there in ACR for couple of days, but today I discovered it was gone from the Presets list in ACR. Vanished. 

Went to create a new group and preset, names exactly corresponsing to ones which dissapeared, and then I get this pop up dialog telling me this (see screenshot).

Question is where is that group and  vanished presets then, I dont see them in ACR?
