You need to be a bit more specific here ...
You originally had two cloned shipping modules ... what were these cloned shipping modules and what are their names now?
You then added a bunch more what did you call them?
If you see all of the shipping modules in the Admin in the Modules ... Shipping ... and can see the right panel and the line below all of the modules that starts with:
Module Directory:
what are the Sort Orders on your shipping modules? Check that they are either all set to 0 or ... that they each have a unique Sort Order and none are set to 0 ...
