Room Search dont find rooms charged before updating to uc_hotel_dev2.x

Hello
First of all Congratulations for the last inprovements in uc_hotel
Second Sorry for my english
Third, the main question, Im trying to build a multihotel site with taxonomies. Ive just updated to de uc_hotel_6.x-2.x-dev to try the new discount module from the 6.x-2.0-beta4 The problem is that the Room Serch block dont find old buildings charged before the updating.
Ive try to ubdate baserates, and availabilities but it still dont find any old building, just the new ones.

the most strange is thet if you pubish them in the frontpage you can see that there is availabitlity for the datas were the block dont find anithing.

Thanks again for youyr developements
