Current settings are saved as a ".png" (Solved)

[ViciousTribble]

Hello

This is my first post here so, noob alert. Let me know if I messed up.
I have a RT-AC3100 with Asuswrt-Merlin Firmware Version:386.3_2.
I was preparing to upgrade and when I saved my current settings, they saved as a ".png".
I hit save a few times and each time was the same; "Settings_RT-AC3100.png".
It should be a ".cfg" correct? Anyone have any ideas?
Thanks in advance for any help.

I really appreciate your help and fast reply. Have a great night.
