See the attached score. Inspect the tablature ties.
* Those marked A, B and 2 are at a similar height above the tablature staff.
* Those marked 1, 3, and 4 are at a lower height.
The reason for the difference appears to be the presence of an untied note at the start of the tie. Surely all ties should be at the same level?
