Red,
As for the red arrows on text....try rt click....size to fit........to lose the red arrows!
RE: Lines Missing.
I am assuming you are exporting to .pdf @ Output Quality = HIGH.
I have had "losses" of sorts using high quality setting.......and now always export to .pdf Output Quality = MEDIUM......with good & consistent results.
Alternately:
You may also want to experiment with the raster/vector/hybrid settings to see if these change your results.
Best,

EDIT:
As for the text in SU...Vs...text in LO......I would say you need to experiment some with the text height vs points in SU.
I prefer using the font heightset somwhere between 3" & 6" depending on the drawing scale set in LO........again something to experiment with.
