Missing or Corrupted Style

[CanadianMacFan]

Hi,

I downloaded the style Minimal Sigalakou from the page User-Contributed Display Styles at https://www.vienna-rss.com/extras/. I unpacked the ZIP file and double-clicked on the file. Instead of installing the style like the other styles I had installed today an error message came up stating "The style minimal sigalakou appears to be missing or corrupted." Vienna then replaces the current style with the Default style.

I'm running Vienna 3.5.6 on macOS Mojave 10.14.6. I tried to download the style, unpack the file, and install it again just in case it somehow became corrupted on the first download but the result was the same the second time.
