Copper flooding in VX2.4

I now have more copper flooding problems in VX 2.4.

Here is the bottom side of a pcb, and the relevant flood is the top one just above XR2. The outline is what the flood should look like, and indeed does in VX 2.2.

See picture below:

If I flood it in VX 2.4 this is what I get:

But this is what I get after flooding. It seems to generate a clearance around the top pad of XR2. One way I can get it to work is if I include the top part as part of the flood, either by modifying the flood outline to include the centre of the top pad of XR2, or add a circle of flood directly on the centre of the top pad of XR2 (so it generates a white x (copper plane indicator) when it floods) as shown below:

There are lots of rules on this pcb (as its mains input!) but this new behaviour seems a bit bizarre. I have noticed other areas that don't flood unless the flood outline includes the centre of the pad. Is it me or is it Pads??!!!!
