When using this module: the following module is missing from the file system: selected_and_unselected_values_formatter in watchdog [#2996871]

I have a lot of

User warning: The following module is missing from the file system: selected_and_unselected_values_formatter. For information about how to fix this, see the documentation page. in _drupal_trigger_error_with_delayed_logging() (line 1143 of public_html/drupal-7/includes/bootstrap.inc).

in my watchdog.

I am using this module and it is working, not missing.
I found out that this happens because the module's folder name does not have the same name as the module files and projectname in the info file. (Thank to aitala: https://www.drupal.org/node/2487215?page=1#comment-12091191)

I solved this by:

renaming the folder selected_and_unselected_values
change the projectname in the info file: project = "selected_and_unselected_values" (normaly added by Drupal org package script)
