Craft Edge

When I cut with my expression the corners of some of the letters do not cut. I have my cricut machine set to low pressure blade depth on 4 and speed on low. I have the computer tell the cricut to cut 2 times. What else can I do? Weeding should be way easier then it is. Please help

i am trying to make a 2 ended arrow to connect two circles such as in a flow chart but do not want them to cut separately. I made one but it cuts all three shapes (2 arrows and a line) separately. does weld fix that problem?
