Unable to draw line or colour fill in a current .xar doc

[KimPen]

Hello, I was working on a image of a 'goat' see first jpeg

Please be patient with me as I am still a novice with using technical terms.
Ok I was able to draw objects, colour fill etc.

Then on the next occasion I am having problems editing or draw new objects to this .xar.

See second jpeg - here I have copied the full figure and paste it as an example of what I am encountering.

Any new object or lines are coming out as red dotted lines without line colour/width or able to colour fill.

What have I done to this .xar that I can't edit etc. Please advice how do I correct this.
Thankyou
