For C++ formatting profiles: Tools->Options->Languages->Application Languages->C/C++->Formatting
I have 4 additional profiles in my config: "2_space_indent", "3_space_indent", "4_space_indent", and "tab indent"
If I export my configuration (Tools->Options->Export/Import Options) and then "Export All Options", and save it to "SlickEditOptions22.zip".
Then close SE, and restart SE with -sc option pointing to an empty directory so that have the default configuration. Using an empty directory with default config is critical to reproducing the issue.
Import the configuration that was just exported.
After the import, only "3_space_indent" is in the formatting profiles, the others are gone.
To reproduce, you can get the 22.0.0 directory as a tarball from support.slickedit.com where I uploaded it under "extra_a".
Copy this 22.0.0 directory to an SE config directory and start SE with -sc option pointing to this directory.
Then perform the export, close SE, start SE with -sc option pointing to fresh new directory, import the config. You will see that some of the formatting profiles are missing.
I did this on x64 Linux with CentOS 7. If needed (may not be required), you can reuse the VM that I uploaded in this post:
