Mysql is not detected

I have a Windows server with Mysql 5.1 (I know it is a very old version, we are waiting for the application update from the supplier).
In May I ran a scan and several vulnerabilities were found on both Mysql and the operating system (rightly so). I’ve patched several vulnerabilities on the server and wanted to check it out.
I relaunched the scan and the MySql vulnerabilities no longer appear, but I didn’t fix anything.
How come? it’s as if my sql is no longer being checked.
I checked the firewall and I have no blocks.

These are the scan parameters
min Qod 70%
Scanner: OpenVAS default
Scan Config: Full and Fast

Hi, I’ll try to explain my problem in detail, I thought the problem was related to the Community version, in reality the NVT appears on both the Community and Enterprise versions

Vulnerability detected

last scan

The scans were performed in the same way, the only difference is that the first scan was done with an outdated version of Openvas, the second was done after the latest updates.
The scan parameters are the same
