You need to join the fixes. Go to the
LEGS button on the FMC and you will see that there are
RTE DISCONTINUITIES in the flightplan, as shown on the screenie below.

Just click on the LSK of the waypoint you want to go to instead of the discontinuity (on my screenie
BOL LSK 3L) then place it on the LSK of the discontinuity (on my screenie LSK 2L).
Whoa, here is your result!

Scroll through the different pages with the
PREV PAGE and
NXT PAGE keys to scroll through all the pages (in my example 3 pages) and remove all the discontinuities.
Hope this helps, and happy flying!
