“Record” feature refuses to capture anything longer than 15 seconds

I have my default set to 15 seconds for my own preference, but when I switched it to 30 seconds it would only capture the first 15 seconds.

When I use the option to record longer clips, for example 2 minutes or 5 minutes, it inly captures 15 seconds.

I have deleted all if my clips and started from scratch, and that hasn’t helped.

Please advise.
