Cant select flex track on RTS7

must first have 2 endpoints in place (turnout or sectional) to add flextrack

i created my track plan by using all sectional track first. Then i went back and deleted a few peices of sectional track, then added my flex track.

After adding flex track, go to tools, modify flex track, and change the radius of track. I do beleive it's under tools?
