Multi-boot boot loaders missing after MacOS update

                          My MacBook Air (2017) currently has 3 OSes: MacOS, Windows, and Ubuntu (making it work was a nightmare). Yesterday when I opened up rEFInd, only MacOS and the Ubuntu stub loader (which, fortunately, still works) was there. All my partitions were still there, but...



...only the MacOS boot loader showed up in the EFI partition.

I suspect that this happened after the recent MacOS update that I did. Now I only have the option to boot into MacOS or Ubuntu.

And for those who are confused by my setup, I used the "alternative solution" in this  question.
