Adding Cross Dissolve Messes Up Video

Hi there,
I like to add a cross dissolve by right clicking in between two butt ended clips, choosing how many frames and selecting Trim Clips. It's worked fine up until now.

Now for some reason, when i do this, the video track goes 12 frames to the right (when selecting 25 frames) and separates from the audio. This creates a big gap between clips in the video track
The audio track moves to the left and creates the 25 frame cross dissolve as it should.

I'm not sure what I've done to it to cause this but I must have clicked on something.

Any ideas? Thanks!
