Aplicación Suite CRM Reports

Good morning.

This week we’ve been having issues with the aor_reports module. It turns out that one of the listview fields ( report_module) is not listed at all ( when it should list all the modules, to select one to operate)

We’ve been doing research and it only happens in this module and only in dev. ( we have another PROD environment where it doesn’t happen , since these changes made have not been uploaded) and we know that some relationship has been affected by operating by deleting some module. This is how we have tried

Check the debug and error trace,
Investigate the non-custom files in aor_reports ( aor_reports.php, etc) , drawing the conclusion that one of the global arrays $app_list_strings does not return any information when it should have the list of all the modules)
We are operating on SuiteCRM: Version 7.12.12 and php 7.

Best regards.
