spacing in MS Word 2000

I made a "normal" from a WP5.1 file to use in Word. The spacing is off. Two spaces after a period in certain sections will look much longer in length than it should be. How can I correct this?

I've already checked un the format tab, paragraph tab, spacing, and before and after boxes have a value of 0 pts.

The spacing seems this way in sections that have a lot of tabs.
