Github recognized my VBA(.bas) file as a FreeBasic

I committed VBA files into my repository, but some of them have been recognized as FreeBasic files, not VBA files.
They have the same extesion (.bas), so I wonder how Github divide them into each category.
Isn’t there any way to make it recognized as a VBA file?

Thank you for your help & take care of your health.

You basically add Linguist definitions in your repository .giattributes file. Here’s the documentation:
