Translations are missing in newer language packs

[BastianHammer]

Issue

I've downloaded multiple language packs. One from November 2025.
When I search like this, I find:

...LangPack8/SuiteCRM_core_de_8_2025_11$ sudo grep -R  "Kontakt erstellen" .
./modules/Leads/language/de_DE.lang.php:    'LNK_NEW_CONTACT' => 'Kontakt erstellen',
./modules/Contacts/language/de_DE.lang.php:    'LNK_NEW_CONTACT' => 'Kontakt erstellen',
./modules/Emails/language/de_DE.lang.php:    'LBL_CREATE_CONTACT' => 'Kontakt erstellen',
./modules/Users/language/de_DE.lang.php:    'LBL_QUICK_CONTACT' => 'Kontakt erstellen',
./modules/Users/language/de_DE.lang.php:    'LBL_CREATE_CONTACT' => 'Kontakt erstellen',
./include/language/de_DE.lang.php:    'LBL_CREATE_CONTACT' => 'Kontakt erstellen',

and I've downloaded a recent one from July 2026, and I see this:

.../LangPack8/de_DE_SuiteCRM_lang_8.10_2026_07$ sudo grep -R "Kontakt erstellen" .
.../LangPack8/de_DE_SuiteCRM_lang_8.10_2026_07$ 

So there have been strings / translations lost.
How can we re-merge them? How can we get them back?
As it stands now, the new translations are worse than the ones from one year ago.
