MKVToolNix problem, audio clicking sound added to remuxed files.

[RoastedGarlic]

Hello, I've been trying to make an mkv with a VP9 video track, Opus audio track, and an srt subtitle. A clicking sound is heard in both channels of the audio track after remuxing. I also tried to forego the srt and make it a webm, and it has the same clicking sound added.

When I made a 30 second clip of the Opus track from the remuxed mkv to post as a example, it sounds fine, no clicking. Why would the Opus track sound fine before muxing, and extracted as a clip after muxing, but have an added clicked sound in the mkv or webm container? Here's a 30 second sample of the mkv: https://a.safe.moe/6Nwew9a.mkv
