H264/265 AAC Premiere Voukoder encode has short silence at the end of each clip

Rendering any of my clips using the attached preset is very often causing what looks like about 10milliseconds of silence at the end of my audio. Big problem for me, since I'm using these clips to loop in a player. Any ideas what's going on here and how to fix? PremPros H264/H265 export doesn't cause this issue. My export format must remain as H264 or preferably H265.

Windows 10
Premier 22.2
Voukoder 10.2

Happening across multiple machines with different hardware.

(Worth noting that this issue has also happened to me across earlier versions of both PP and Voukoder)

Thanks for the advice.
