A good point, I've checked the research tab at the crafting station and it's indeed called "Analysieren". I also took a look at the deconstruction tab and it's called "Verwerten", not "Zerlegen".
This leads to the following changes
Lua Code:
["SI_ITEMSAVER_FILTERS_DECONSTRUCTION_LABEL"] = "Verwertung filtern?",
["SI_ITEMSAVER_FILTERS_DECONSTRUCTION_TOOLTIP"] = "Sollen die geschützten Gegenstände beim Verwerten an der Handwerksstation verborgen werden?",
["SI_ITEMSAVER_FILTERS_RESEARCH_LABEL"] = "Analyse filtern?",
["SI_ITEMSAVER_FILTERS_RESEARCH_TOOLTIP"] = "Sollen die geschützten Gegenstände beim Analysieren an der Handwerksstation verborgen werden?",
