Can't Trim Parts of Videos that are Longer than 24 Hours

I've been making a highlight compilation of a long Twitch stream. The program was working great for the first 24 hours, but after that, when I try trimming parts of the video after the 24 hour mark, I encounter a problem. When adding a day on the timestamp (1:00:20:45 for example), when I click OK, the program omits the day part. Is there any workaround for this?
