Bug With Crawl Anchors Option

I’ve imported a few hundred urls into a project and am using the crawl anchors option to generate anchors from the title of the pages. The only option selected is “add <title> as anchor”.
Once it’s finished crawling and I inspect the anchors, everything looks fine. There are 348 urls.
Click ok to close the project. When I re-open the project there are now 700+ urls and the software has added extra urls. For example:
Actual url: https://www.mydomain.com/dog-training/#Dog Training
Extra url added: http://24-7 Dog Training in Atlanta
It seems to be making extra urls from the page title. The format in the page title is
Dog Training | 24-7 Dog Training In Atlanta
Is there a workaround for this?
Thanks
