It sounds like you were in a nav track mode where it limits the banks to 10 deg of correction. This is completely normal for nav track mode. The computer was designed to compute intercept angles for proper nav track. If you refer to that attached file page 40 it will outline how to set up the system for a RNAV intercept/capture. As long as the computer has the proper setup for intercept/capture you should not experience the shallow bank limit.
