Hanging (unconnected) Label but no ERC

I have a “hanging” label–e.g. one that does not connect to anything. This is an error and I would assume that ERC would catch it but it did not. (Look for UV_GND_2 and UV_GND_1 in the attachment)
In fact it should connect to ground and I could just draw it directly this way but for descriptive purposes I drafted it as shown, connecting to a label. Easy to fix but I would hope that ERC would catch these issues (In fact I had already cut the board wrong!).
Is this a bug, some hidden parameter I did not code, or am I expecting too much from ERC?

Thanks Fritz

I want to close this topic. I upgraded to 7.0.2 and the issue went away (but several new warnings now appear)
thanks
