Bug: Error causing icons to not display correctly, Display rules being reset to defaults with errors

[ZappedSi]

My issues shares similarities with #359

Issue 1:

When editing display rule fields I have not gotten Marker Color to accept any hexadecimal colors, and often times colors explicitly stated to be acceptable (ex. cadetblue) and both Marker color and Shape will both intermittently

• Not update the preview until Save & Close is pressed
• revert to a muted red and the default shape
• not do anything at all

Issue 2:

When editing display rule fields, the Marker Icon Properties window closed and the errors below appeared. Upon attempting to open the properties again I got the second error. On the third attempt to open the Marker Icon Properties I was greeted to the same 3 + default display rules that were there on install. This has happened three times with no unusual activity or interactions before it breaks, erasing my work each time.

The errors:

Regarding issue 1, see #188 -- hex colors, and actually most web color names, are not currently supported. It's a top asked fix and I'll get to it in a high priority.
Regarding issue 2, can you elaborate what input causes this?
It might help if you test this in the just-released 6.0.3, which fixes a few edge cases with display rules.
