Column default values are wiped when importing documents through TemplateSelector dialog

[Remi749]

Describe the bug
This is not to be confused with the default values that can be directly set to SiteFields for a document library. This is the Default column values that can be set on the library for folders or subfolders: "Document library settings > Column default value settings".

When importing a document through the TemplateSelector library command, the values are set and seems to work as intended. When trying to edit a value through the list dialog and saving that change, the columns that had default values are wiped, this can also be seen in the version log (see image below). Default values set directly to SiteFields are not wiped.

Example of default values set on the library:

To Reproduce
Steps to reproduce the behavior:

1. Go to a document library
2. Add default values to columns "Document library settings > Column default value settings"
3. Import document through the TemplateSelector library command
4. Edit values through list dialog
5. Witness bug

Expected behavior
Default values should not be wiped. The bug probably has to do with the way we create the document through the TemplateSelector.
