Dolphin Android not recognizing inputs when binding. Input device is Keyboard

[digitalguy]

So I have my controller set on my phone, Galaxy S9, and the input device for it says Keyboard (I'm not using a wireless controller). I can navigate my phone and the Android Dolphin app UI with the controller fine. But when it comes to key mapping the inputs in Dolphin, it does not recognize any of them. Other emulators I have on my phone however do recognize my inputs when binding, letting me play games on there with my controller. Except for Dolphin. Odd... Know how to fix this?
