Old DSN cannot be find to import when old ODBC version is uninstalled and new version installed in Excel

I'm not sure is this related to ODBC or Excel, but let me report.

I have first created DSN with "ODBC Data Source (32/64 bit) " and installed from https://downloads.mariadb.org/connector-odbc/ MariaDB ODBC 3.13.
After that I have removed the old version and installed from source (latest one with patch of interest).
During installation I clicked option "Allow old user DNS the same name ..." (or something similar).
Now I'm not able to remove old DSN even when ODBC Data Source app is started as administrator:

And reason for that is that is using 32 bit version.
There is also 64 bit version where we can see that DSN exists and can be removed

However, when I tried to look for DSN there are 2 ways (ODBC-326):

• Import from Data Connection Wizard
• Import from Microsoft Query
  there is no DSN for mariadb-server

1. Data Connection Wizard

2. Microsoft Query

Additionally, we cannot add new DSN if old DSN exists (no MariaDB ODBC option to use).
If we remove old version, we can add new one:
