How to fix computer names in SQUID?

Question

Squid

Good afternoon. It was not necessary to deal with a squid before. This proxy is installed on one company, I look at squid-reports, and I don’t understand what is displayed there. The fact is that the names of the working machines were chosen automatically, and it is not clear where whose. I corrected the names of the machines for intuitive ones, but in squid-reports they are still displayed in the old way. Tried clearing cache with squid -z and deleting swap files. Nothing has changed. CHADNT?
