Hi,
This just sounds like settings that need to be changed, when you are in the application, head over to the "Visual Styles" tool on the right hand side (Pair of sunglasses), in here, you will notice pretty much all the things you are requesting. Switch between the 4 tabs at the top, to correctly assign all of your visual styles.
Hope this helps!
Hi markvillarpenduscoin,
It would be good to know what platform you're using (Web / Windows / iOS). Touch platforms like iOS and touch-compatible Windows machines have a different interface for things like drawing lines. If you're using touch, let us know and I can explain more.
MItchell's comment is good, assuming your edges somehow got turned off in Visual Styles (thanks for the assist, Mitchell!). If this doesn't help, we'd need to know the platform as I mentioned above, and ideally a video of the issue you're having so we can better assist.
Thanks,
