Check your stems before mixing.
Most mixes get delayed by the export, not the mixing. Drop your stems here and see exactly what a mixing engineer would flag in the first ten seconds — sample rate, bit depth, length mismatch, peak level, leading silence.

What to fix
Stems clean and still not sitting right?
That part is the mix. Single track from $150, unlimited revisions inside the agreed direction, 5 days on the clock.

How the numbers are read. Sample rate, bit depth, channel count and length come straight from the file header, so they are exact. Peak, crest factor and leading silence are measured by decoding the audio in your browser — files over 60 MB are skipped for those columns to keep the page responsive.
Crest factor is the useful one. It is the gap between the loudest peak and the average level. A raw stem usually sits at 12–20 dB. Under 8 dB means something was already limiting the channel before export, and no mix can put that transient back. A peak at 0 dBFS with a healthy crest factor is fine; a peak at −1 dBFS with a 5 dB crest factor is not.
Why bit depth matters. A 16-bit export throws away the low-level detail a mix rides on. If your DAW was at 24-bit and the file says 16, the export settings changed somewhere between the session and the folder.
First export? How to export stems for mixing covers the settings that produce a set like this.
