Typo3 lumogooglemaps extension (problem in adding several markers and editing the longitude and latitude fields)

This is a very nice extension which is based on tt_address. You have the possibility to add several markers on a predefined map and when you click on them, a nice editable info (information from the tt_address records) box pops up.

I first installed lumogooglemaps and afterwards tt_address. This is why I wasn't able to add multiple records in the tt_address sysfolder and also the longitude and latitude fields weren't displayed. So, first install tt_address and then lumogooglemaps.
