Error when searching for double spaces in Studio 2022

Dear all, 

I hope you've had a good start in the new year! I'm writing you because I've noticed that in the last weeks the search for double spaces (via search and replace) in Studio 2022 is not working at all. I use it very often after dictating with Dragon Naturally Speaking. Recently, when I perform the search, Studio seems to find a random groups of characters instead of double spaces (and not always the same characters). Please see the images for reference. I also tried to use regular expressions for the search, but the result is the same. The search for other words/characters works fine.
