FindTextInLocalizationTable can't find a translation to an entry when the translation is the same as the looked up key because FTextLocalizationManager::DisplayStringLookupTable don't keep entries that have the same values on both languages. This behavior is not how it previously worked and might lead to unexpected/hard to track bugs, as described by the licensee.
Please refer to the licensee's repro project.
Steps to Reproduce:
-Start PIE session in English
-Observe, that the first two author-at-source texts are correctly displayed in the upper left corner (Ok, Abort)
-Observe, that the second pair of text, referencing the first two via FindFText are also correct (Ok, Abort)
-Set "German" as game preview language in settings
-Start a Standalone Session
-Observe, that the first two author-at-source texts are correctly displayed in German (Ok, Abbrechen)
-Observe, that in the second pair of text, only "Abbrechen" is displayed, which differs from the English source, while "Ok" (which equals the English source) is empty
