This means as soon as you switch a requestor "off", or you remove any requests, it becomes a provider. This should never happen normally, but happens regularly with this mod.
A fix would be to set as very high provide threshold for requester combinators. It might be a good idea to also set a high request threshold for providers, to make sure these are providers.
If this is ot done, the selection of "provider" or §requester" at the top makes little sense, as it doesn't actually do anything.
