SUMMARY
G'MIC-Qt plugin "Color Presets" is not working properly, specifically when changing LUTs Pack to a different one than the one selected by default ("PIXLS.US") - upon change the available "Presets" remain the same as well as the icon representing the LUTs Pack. Moreover, as the LUTs Pack is changed to any other than the default one, changing the "Presets" makes actually no impact on the photo. "Presets" work only when "PIXLS.US" LUTs Pack is selected.

STEPS TO REPRODUCE
1. Open a photo in Image Editor and choose G'MIC-qt plugin/tool ("Effects" section)
2. In "Available filters", choose "Colors" and then "Color Presets" 
3. By default, "PIXLS.US" LUTs Pack is chosen. Try to change to any of its "Presets" - all work fine (each preset does its thing to the photo).
4. Change the LUTs Pack to any other possible selection, eg. "ON1 Photography" and then list available "Presets" for this LUT Pack -> they are the same as for the "PIXLS.US" LUT Pack (but should be different - ON1 has different names etc.), which is bad. Then choose any of these presets and observe photo - nothing changes. The LUTs Pack icon visible at the bottom also stay the same - as it was for the "PIXLS.US" pack. 

OBSERVED RESULT
Changing "LUTs Pack" does not work - the available "Presets" stay the same as for the default LUT Pack. Updating filters from Internet, within the G'MIC-qt tool GUI does not change a thing. 

EXPECTED RESULT
Changing "LUTs Pack" enables subsequent choice of a desired preset corresponding to the given "LUT Pack"
