Logic Pro iPad - Cannot delete Third Party AUv3 Plugin Presets

From the browser, you can delete User Plugin Presets for native Logic Pro for iPad presets by clicking the "More" (...) button at the bottom, however, when you save a new plugin preset for a non-native plugin (like TAL-U-NO-LX) the preset will also be created in a user folder but you cannot delete these Plugin Presets.

Why is that? Is there a work around? I can't even rename these Plugin Presets. Normally you'd see "Delete" above "Save Patch for Selected Track..." in the image below.
