Ask whether the-sharp in the url link will be unfriendly to the website.

there is a problem. When I share my blog on some websites and post a link, I usually generate something with an icon and description, but my blog can only be crawled to the initialization content of the title tag. The page I share actually dynamically modifies title, but generates a title, link that is not modified like this

.
http://xxx/-sharp/p?sub=ioio

so I have tested the same domain name without-sharp, which seems to work, but it is still not enough for me to understand the reason. Please give me some advice. Thank you.
