Unfortunately, this isn't a problem within the metas.
However, it does appear to be a problem with the plugin inside Ubiquity.
The mechanism is that the metapackages call the packages within the meta
as dependencies. However, if one of those packages is marked for
uninstallation (essentially what Ubiquity does in this case), then it
marks the metapackage the package is pulled-in from for uninstallation
as well. This then flags the apt system that all of those packages
(which are considered dependencies of the meta) are "no longer needed".
Then, when Ubiquity calls an "apt autoremove" at the end of
installation, it removes those packages that have been deemed as "no
longer needed".
This is a change from the intended behavior which had previously worked.
I'm not sure when the change occurred, but there definitely needs to be
a fix in place before 20.04. I will add this bug to the 19.10 release
notes.

Title:
Ubuntu Studio 19.10 Installer Causes Wanted Programs to be Removed
Status in ubiquity package in Ubuntu:
Confirmed
Status in ubuntustudio-meta package in Ubuntu:
Invalid
Bug description:
Ubuntu Studio's Installer has a feature where you can select and
deselect programs you would like to be pre-installed on your system.
However, whenever I deselect some programs, after I finish installing
the system and then boot into it for the first time apt wants to
remove a load of my programs with its autoremove feature.
This includes programs I do intend to use and did not deselect. For
example; I deselected Blender, and then Kdenlive (which I do want to
use, and hadn't deselected) also got deleted.
I explain it better in a video I did on Ubuntu Studio 19.10:

is where I begin to explain the problem.
Thanks in Advance!
