Tonnie:

You could try this -

1. From the "Lead Sheet Window" (click on the green, tied 1/8th note icon), click the "Opt" button
2. That gives you the "Lead Sheet Options" window
3. In the box that says "Fakesheet bars/line", set the line you are having trouble with to one less bar
4. For example, if the whole song is set to 4 bars per line, and the problem slash chord is on line 3, you could set the bars/line to this: 4,4,3,5,4,4,4,4

5. That would give you more room on line 3 but less room on line 4
6. You may have to adjust the bars/line of additional lines to make it look right

Good luck!
