This happened because the audio duration has more than 1min difference from the scheduled one, specifically the audio duration is 13min 35s while the scheduled one is 17m 44s. Usually this happens when there are lost samples (cpu can not handle all the samples coming from the SDR), if you face this a lot then check the logs for multiple O’s like “OOOOOO”, this means that there are lost samples.
If the lost samples is the case then you can decrease the sample rate you use, check also this thread.
