Relationship verb phrases are appearing wrapped, with a horizontal line

On a model we recently purchased and loaded into ER Studio, some of the verb phrases are longish, and they are being displayed wrapped over two lines, with a long horizontal black line between the two lines of text.   I cannot find anywhere to prevent wrapping.  In fact, the wrapping isn't actually a problem but the horizontal black line is.    I cannot replicate it on our other models/diagrams when entering long verb phrases.
