Your method for using Personal Libraries is not good. You will end up with a vast number of Personal Libraries, each with one symbol only.
What you have done is made each symbol a library.
Kicad is only able to create libraries. Folders in which to place Personal Libraries need to be created with your Operating System (in your case: Windows).
When you have created and named folders, and folders inside folders, you then use Kicad to create the Libraries to place in your Folders.
In Your case, you will create one library called TVT.
You then place all the symbols you wish into the one TVT library. Using this method will give you the below result when you open your Symbol Library Browser:
Highlighting your TVT library will now show all your symbols in the one library.
To transfer your symbols from their current libraries to one single library, it is easiest to open the symbol in the Symbol Editor then:
File > Save Copy as > Edit the name by removing the “TVT_” and scroll to and highlight your new TVT library. press OK.
This FAQ: https://forum.kicad.info/t/kicad-7-8-beginners-guide-to-personal-symbol-and-footprint-libraries/38738/1 hopefully will explain all.
If you have any questions, please ask.
