Yes that is a bit strange and should not happen. It probably happens because it tries to adjust " the left overs ".
What I mean is, if you have scheme columns width at 1 meter interval and the length of 1 wall section is 9.67 m as example and the next connection wall length is 4.36 m ( random numbers ) it won't be able to divide this clean by 1 meter obviously.
I suggest to draw each section of the curtain wall as separate entity this way it is more flexible to adjust each starting point.
