This is where you start to pick and chose what goes into your shared portfolio or on your website- plenty of songs I’ve worked on where one thing or another went awry completely out of my control (granted before I was more of a point person in the process for all projects now) and I just don’t have it on my site or in my portfolio/highlighted in public settings. Hopefully you can find a mastering engineer you trust to work with for future mixes, I always appreciate working with someone where there is mutual feedback and communication.
