Cutter Tool Not Working - URGENT

Hello, I just started having this problem a few minutes ago on Storyboard Pro 2.1.

When I select the cutter tool, I used to just hit “T” to trim any lines, but recently, it just highlights the line in green and doesn’t trim it automatically. I was just using it yesterday and it was working correctly, so I don’t know what happened. I tried restarting the program and my wacom mobile studio pro 13, but it still persists. I checked the tool properties, and I have the lasso tool selected with the “cut multiple lines option” selected, so all the settings look the same, but it refuses to behave. How can I fix this? Please help!!!
