Adding table to floor map using Entities

Please help!! I tried adding a table to my already existing map, however after I added an entity and went to select the entity in the entity screens, entity list it only shoed 1 as an option. I already have a table one. So, after a few attempts I deleted the entity type and tried to start over. Now, all the entity list show all 1’s!! So, now I can’t have more than one table open at a time! How can I fix this?

Add the new Tables to the Entity List for the Entity Screen …
