use of custom mode - help please

[ajay-gh]

When I use custom mode settings like (just an example) : { "amazon.de": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:83.0) Gecko/20100101 Firefox/88.0", "*": [ "UA1", UA2, ... ] } everything works exactly as expected.

However, when I replace the "*" in the above example by "_" (per site UA selection, as explained in the description in the options window), then I get random UA agent strings, but no longer the ones I defined within the brackets. Is this a bug, or a problem o my settings ?
