Stats shows still old version after upgrade HAProxy

Hello All,
I have small cosmetic problem.
I sucessfully upgraded my HAProxy version 1.8.12-8a200c7 to HAProxy 2.3.3
All works correct, but stats page still shows old version.
haproxy -v shows:
HA-Proxy version 2.3.3-9233c21

Restarting the server don’t resolve the issue.
Any ideas??
I use CentOS 7.

Thanks for every help

Sounds like you may have two binaries installed, the old and the new.

Maybe try a find to see if you can find them both: find / -name haproxy

I deleted all the files and directories named haproxy and I installed HAProxy again, this time with SYSTEMD and now everything is displayed correctly.
Thanks for advice.
