SNipet to add multiple Google Fonts

Hello again,

I am trying to add multiple Google Fonts using the Snippets and method as described here:
https://docs.generatepress.com/article/customizing-the-google-font-list/

This has worked totally fine for one font.

But I am doing something wrong with adding the second font.
I added a second snippet, but the snippet broke the site...saying it was repeating the code:

PHP Fatal error: Cannot redeclare tu_add_google_fonts() (previously
declared in
/home/jl_webalchemy/staging.pivotacupt.com/wp-content/plugins/code-snippets/php/ snippet-ops.php(361)
: eval()'d code:2) in
/home/jl_webalchemy/staging.pivotacupt.com/wp-content/plugins/code-snippets/php/ snippet-ops.php(361)
: eval()'d code on line 10

Can you guide me in how to add more than one font to the customiser please?

And how can I remove this info from the plugin, as every time I delete and reinstall, it pulls the old info through and crashes the site again.
Right now I have to rename the plugin via FTP to get the site to load.

Cheers!
john
