After Update illustrator pen tool not working properlly

Hi everyone, 
After the latest Illustrator update, ver 29.0 the pen tool simply stopped working properlly. 
The paths are no longer closing even when I go back to the first node, and even on the lowest smoothing seeting it is changing the shape so much is impossible to get the original shapes i am attempting to create, it was NOT doing this two days ago before I updated. 
Is there any new hidden setting that i dont know about? Does anyone have any suggestions on what to do ?
This tool is one of the most important ones for my work and without it working it will impact the results so much. 

(heres how its looking after i reset the tool config. and tried making a shape, but it interfered so much its not the same shape i was attempting to make at all)
