My sitemaps disappeared

Web Scraper version: 0.4.01
Chrome version: 74.0.37
OS: Windows 10

Anyone can help?

I presume you are not able to create a new one as well. This usually can be fixed with a quick re-start of the computer.

I can create new ones but the old disappeared. Restart did not solve the problem

Anybody could help ?

Any chance to get this fixed ?
