Rough sketching changes when dimensions are applied.

Hi,

I have  asked this question in the past and thought I had an answer, but I didn't.  I am using SW 2018 standard edition.  When I create a rough sketch and try to add the correct dimensions to it, it sometimes changes the positions of the previous lines.  I have three pictures that hopefully show the problem.  I am a furniture maker and I am trying to extrude a tenon on the end of a curved chair back.   The tenon I am trying to make will be 3/8" x 2" and 1" from the end.  I drew the 1" line, then I did the upper half of the tenon which is 3/16", but when I tried to draw the horizontal line, which was 0.54" to 2", the result I got was picture three.  What am I doing wrong??  This is not the first time I have had this type of problem, it has happened to me over and over again.  Someone can say that I have a center line down the middle of the part and that is causing the problem, but that is not the case.  Other times there wasn't any center line. 

Thanks for any help you can give me.

Bob
