Why did the LCIA result (freshwater ecotoxicity impact category) contributions amount to more than 100%?

Question

I got 3 major contributors to freshwater ecotoxicity impact category, and the total results amount to more than 100%. How is that possible? (I have run several times but all other impact categories gave normal total 100% but only this category gave more than 100%). What should I do?

Contributor 1: 74.5%

Contributor 2: 34.1%

Contributor 3: 0.67%

Answer 1

I needed to remove the link to (maybe) the screenshot as it did not work - you could have smaller contributors that have a positive contribution to water scarcity as they release water?
