Sadly these two indicators seem to interfere with each other:
if you have both on one screen and activate Pivot 1.3: after a second or two the letters next to the lines disappear and only the lines remain.
Is there any chance you could change one of them in such a way that both work on the same screen?
I think the probolem lies with the HiLow-indicator because other objects (like rectangles) also disappear from the screen when this indicator is used.
