Single hyphen in a URL text is recognized as double hyphens

[shin educ]

I output a PDF file with PowerPoint export function.

In PowerPoint, I filled in two URL texts. (Image 1)

When I opened the output PDF file with Acrobat Reader, the second URL was recognized as a hyperlink with a double hyphen. (Image 2)

Is this a known bug of Acrobat Reader? Also, is there a workaround?

By the way, this phenomenon does not reproduce when the PDF is opened with a browser such as google chrome.

The OS/software and its version in which the phenomenon occurred are as follows.
* OS: Windows 10 Pro (19043.1110)
* Power point: version 2107 (build 14228.20250)
* Acrobat Reader: 21.5.20060.443953
