Native Language

I was accepting some suggestion 3 days ago, and I wanted to copy them to the master branch by downloading each and running a script on them.
I downloaded the Lib5.0 file and the master file, merged them with msgmerge, and uploaded the output file directly to master. I noticed then that the "system user" user did overwrite on all of them with empty translations! Is that normal? If not, then what would be the problem? Is it because of templates?

The original mail sent to the i18n mailing list: http://listarchives.libreoffice.org/global/l10n/msg09592.html
Lists of strings:

• https://translations.documentfoundation.org/ar/libo50_ui/translate/#filter=user-suggestions-accepted&user=Damascene (Some are still there)
• https://translations.documentfoundation.org/ar/libo50_ui/translate/#filter=user-suggestions-rejected&user=Damascene

Note: The files I downloaded from Pootle (Libo5.0-UI) project didn't contain the strings in the two links above, looks like Pootle update them from time to time.
