Video time displayed incorrectly after 60 minutes

macOS version: 10.14.6
Kap version: 3.2.2, installed via Homebrew cask

Videos recorded that are over an hour in length roll around to zero instead of counting up from 60 (in minutes), or displaying with an hours digit, e.g. this recorded video shows it's 4:17.83 in length (i.e. four minutes), but it should show 64:17.83 or 1:04:17.83. The time displayed on hover while seeking via the time bar is correct, however.
