[Black bars covering up LED bar graph.]

Yeah, each bar is linked to a CO2 sensor, linearized from a 4-20 mA signal. when the CO2 gets high enough, the bars should show red, but on rooms 4, 6, and 7 they stop  midway through the yellow. I'm curious if there's a maximum number of blinking/changing lights the screen allows.

Need help debugging a Visilogic project.

 

PLC is a V700

I'm trying to put in bar graphs, and the screen keeps putting black bars up on the right side of the graphs. I've tried deleting and remaking them, but the black bars keep reappearing on different lines- they're not linked to any one input. Pictures are shown in the link below. 

Any ideas on why this might be happening?
