Fingerings with circle are incorrectly positioned

Score from 2.3.2 (here attached)

2 problems:

Measure 2 and 6: fingering i with a circle is higher positioned, should be aligned with other fingering.
I suppose the auto position algorithm overvalues the necessary space for the circle.

Measure 1 and 5: why is the fingering i of the before last note so low? And why is the m of the last note so high?
