Filter showing throughout entire video

In a video I was creating I put a text filter on in a trimmed section. It appears in the entire video and doesn’t show up as a filter in any part of the video except for the trimmed section.

I assume you mean; “It appears in the entire video rather than as a filter in the trimmed section.”

If not, please re describe the issue.
Otherwise show us a screen shot of how you applied the filter, thanks.
