Location mark does not display in GMap block in D7

Hi,
I'm marking this as a BUG because in D6 I have exactly the same functionality and it works. In D7 it doesn't work.

The Setup:
1) Location + Gmap module.
2) Gmap block is active and displaying in the sidebar on node full view.
3) End users enter addresses in 2 Location fields (Street and City... for example "31 Fleet Street, London") -- all other parameters (Country, Region, Postcode) are pre-selected (enforced) because this is a very local website. They do not place any markers on the GMap because the system will do that for them automatically, based on Street address that they enter.

Result: When the node is saved, on the node view sidebar we see a GMap block with the Location Mark automatically appearing (notice: they did not manually place any markers. They only entered their street address).

In D6 this works like a charm. In D7 it doesn't work.

PS: I also noticed that in D6 it will capture the address with a comma, like this: 31 Fleet Street, London. But in D7, it captures the address without the comma, like this: 31 Fleet Street London. Maybe this is the reason why GMap is unable to auto-place the location marker.
