Polygon mask cuts off text
Hello, I am trying to make a Star Wars-like intro. I'm using Premiere Pro 2020, and I'm using a fade with a 4-point polygon mask. Here's what I'm trying to do...


It's looking good so far, but the problem is that the text is all cut off! It's only able to mask a small square out of the entire title crawl, which is several lines long. Applying the masking effect restricted the text for some reason. Here's another screenshot of before I adjusted the polygon...

What's going on? As soon as I click to create the masking effect the text seems to restrict itself into a much, much smaller area.
I hope this explains it all. Cheers!

Edit: The first two screenshots are as I apply the mask on the frame shown in the third screenshot, if that clears anything up. Scrolling through the frames still shows the crawl but in a very small area.
