Frame Rate not Processing Correctly in Premiere Pro

We have a video file (.avi) with properties of 60 fps in file explorer. When opening the video in VLC, it plays at the correct visual rate and has the correct duration. When importing into Adobe Premiere Pro, Premiere recognizes the file as 60 fps and originally displays the correct playback duration. The visual rate, however, is not correct. A video of a clock plays twice as fast as it should. This is true even once the video is exported. When changing the video to 30 fps (via "Interpret Footage"), the video played back visually at the correct rate, 1 minute of playback equaled 1 minute of clock time, but the total duration of the video doubled.

Is Premiere adding frames? Is there another way to adjust frame rate? I have not had this problem before, and I am struggling to find resources for this online. Any suggestions would be appreciated.

Thank you!
