"Recording remuxed, but the file may be incomplete" PCM 32 Bit Float audio codec

[IssacI69]

I've been testing out new settings for recording in OBS, and I want to use the "FFmpeg PCM (32-bit float)" audio codec in the recording, but I'm having this weird thing where when I remux the .mkv file to .mp4 in obs, I get a popup that says "Recording remuxed, but the file may be incomplete". It's interesting because the original recording, the .mkv file, is totally fine. It's just when I remux it to .mp4 with that same codec. This goes for any of the other FFmpeg PCM audio codecs. Someone, please help

MP4 media container format has only limited set of codecs that are supported. Uncompressed audio not included. This is by standard. Some versions of MOV container supports uncompressed audio.

So I would want to use MOV or MKV instead for PCM audio? Because I heard that FFmpeg doesn't support PCM inside of an MP4.
