I am the person who had applied on contributing to the Hungarian translation of FlashFXP. The case is that I exported the strings to CSV from TsiLang Files Editor, because by importing it to
Alchemy Catalyst I wanted to speed up the progress. After completing the translation I imported the CSV file to TsiLang Files Editor, and several resources, like the repeating Dialogs disappeared from the tree
It's a pity, that the export/import feature is not really working properly in TsiLang Editor.
So there is nothing else to do than to translate the strings manually

It is in progress, but requires much more time.
