Video in Cubase; frame rate mismatch

Cubase actually allowed me to import a video file without confirming the frame rate?

So it just imported the video and now I have a frame rate mismatch.

Why didn’t I get a dialog box saying “your video is 30fps, but your project is set to 24fps. Would you like to keep current frame rate or change it to video file?” !?!?!?!?!?!?!

BTW, the ‘Set to Video fps’ in the Project Setup menu doesn’t work. The video was a regular .mp4 file
