Cannot Align Documents

Hello,

I'm a bit new to working with SDL Trados and I'm having some alignment issues that I don't know how to resolve. I'm trying to align an English Word file with a Spanish Word file. The problem is that some segments in the target column are allowing 2 sentences even though they are separated by a period. This is causing a lot of disalignment that will take a lot of time to manually correct. Is there any way to solve this?

Thank you for your help!
