Problem to merge segments both into Trados Studio and Live

Good morning,

I am a Freelancer Translator and I'm working with Trados Studio and Trados Live with another group of people and while working we found out that we cannot merge segments both into Trados Studio and Trados Live. 

We already activated the option into the settings to permit the merging but into the actual translation project, it doesn't work. 

We kindly ask if there is any way to solve this problem. 

Thank you in advance

Matilde
