I update from OSX El Capitan to macOS Sierra yesterday. Now when I open PDFs containing highlights there are 'double highlights', ie. the original highlight and an additional highlight which is offset slightly. This only happens for some highlights.
See example in picture below. This page should contain 4 highlights (the title of the figure, the p1 and p2 in lower graph, and part of the third last paragraph), but 7 highlights are displayed. Only the last three highlights have "doppelgängers". These additional highlights are offset (down and to the left).
Any suggestions how to fix this?
