@ZED ,
How did you create the default connector line? It's recommended to modify the connector back.
- Please backup your files first.
- Open one file, go to Shapes at right panel > Click More Shapes > Show document Stencil.
- Right click Dynamic connector > Edit Master > Edit Master Shapes, then you may open the Editing mode.
- Please set the connector as your needs. Such as right click the connector to open Format Shape, set color, arrow and other styles.
- When you are finished, close the editing window,not the application (A X at the upper right).
More information, please refer to "Visio 2013 Connectors - Can we change these?"
Any questions, please feel free to let me know.
