Hi Michael,
I believe you know what are the objects, how to draw them, change colors etc. Of course if you draw a small trendline on a 1 min chart and change to weekly you will see nothing.
One more thing is visualization. So if you draw a trendline and then select it, right click on it and go trendline properties and visualization and instead of "show on all timeframes" you have a specific time frame selected then it is not going to show on another timeframe.
In case none of the above is the case this is what I would do to find out what is wrong. First I would start with a chart without template. If the problem persists then it is not a template problem.
If it works, then I would try with a template that I would make myself. Add a couple of ema's change candle color and save it under a stupid name. Then check if the objects disappear again.
If everything is ok I would try to replicate Marc's template. There are no more than 10 indicators on it and again save it under a different name.
If nothing of the above works then I am afraid you have to unistall the platform, delete the directory in which it was installed and start over again.
If you need more help do not hesitate to contact me.
Good luck.

Pixie, some objects like circle, require that you after selecting it on the panel, will click on the chart with left button, and, while button is still pressed, will drag mouse around, allowing for a circle diameter to be selected (actually two diameters, because it is an oval). Have a look at your chart's objects - you may see those invisible objects in that list.
