Hiding thumbnails title on Phantom module doesn’t work

Hello,

I’m trying to hide thumbnails titles on phantom module. I went to presets settings and “Thumbnails Title”, but when I pick “None” from “Display Thumbnails Title” dropdown and click Save, the settings are back to “Label Over Image” and they are not changed. I’m able to change them to “Label Under Image” or “Tooltip” and it’s working fine, but when I select “None” then it automatically goes back to different settings.

I will be very thankful for any tips to overcome this issue.
