What version of IOS IPS are you running?

Version 3 signatures had a fixed memory limit of 64K per signature engine. If you attempted to enable more signatures that the available memory, the engine would fail to build and the signatures wouldn't load.

Check your log when you enable IPS on your first interface, it should give you plenty of information.
