Why does my text move outside of the bounding box when editing text in Adobe DC?

When add text to this line or any line, the Freight pushes to the left outsind of my bounder box, is there a work around or setting to correct?  See the image below to demonstrate, just adding the word not, moves Freight outside the left box limit.  Help please!  

There is no such thing as Adobe DC... moved to the Acrobat forum
