This warning occurs when both of the following are true for two tendon segments that share a Profile Point 2:

1. The tendon segments have the Position Profile Point 2 for equal balance loads option checked, and
2. One, and only one, of the tendon segments is flat (that is, the values for Profile Point 1 and Profile Point 2 produce a flat tendon segment: this usually occurs when the two values are equal).

The Position Profile Point 2 for equal balance loads option is intended to move the plan position of Profile Point 2 so that the uplift is equal for both tendon segments. This is not possible when one tendon segment is flat (zero drape) as there is no uplift in that tendon segment.
