Cursors missing from a Plot initially hidden using Property Nodes

My application use a Global Variable from which I am taking the values that constantly change and show them in a main Plot; in other words, while one sub-vi is performing some calculations a parallel sequence of the main program is being performed (by means of a while loop...). In this loop, I use Property Nodes to make a kind of live perform on the main Plot, doing this at the same time with a hidden Plot that belong to a specific sensor, then I continue with the rest of the hidden Plots... The Cursors of the main Plot are shown but when some of the hidden Plots shows up, there is just one Cursor (I guess the last one...). The weird is that the Property Nodes of both Plots (the main Plot and the hidden one in turn...) are being updated at the same time but the difference is just that one Plot is hidden. I have debugged my application by intentional taking out the Property Nodes of the Hidden Plot from the Sequence Stage and put it beside the Property Nodes of the Main Plot, and I get the same result; then I hidden the main Plot and show the other Plot and the result is the same, the missing Cursors are in the main Plot which is kept hidden now... It seems to be that if the Plot is hidden, and some properties are changed is not not reflected because the hidden condition of the Plot.
I have attached a file with some screenshots of my application to give you a better idea on my explanation.

Your help is welcome...
Thanks in advance
