Help with filtering RG

I used Bubble to create my Foreign language app, but I’m stuck on something. I am using an RG to filter through all the available language exchanges. Upon signup, the user sets his native language. In the “scheduling” page is the RG, there is a dropdown fill of every foreign language you want to learn. For example, the current user’s native language is English and he clicks on the dropdown to learn “Chinese” in the “scheduling” page. The RG works in that it shows all the English→Chinese language exchanges, the only problem is that it is not showing the Chinese→English exchanges. For example, if a Chinese user, wants to learn English, he would click on dropdown and the RG would show all of the Chinese→English exchanges, but not the English→Chinese exchanges. I want the RG to show both directions when relevant, since both types of exchanges would be valuable to your users.

How do I achieve this?

How does your data structure look like? As in, how are you storing the data you are displaying? Is it in a table or option set? What filters do you apply to the Data Source of your Repeating Group?

It’d be super helpful if you could share screenshots from the editor.
