There are two frames in my project, Part Reference and Techman TM14S Base. It worked fine in the beginning.

When I opened the project next time, I noticed that the frames cannot be found in the machining settings. It only showed the new-created frame.

Is it a bug or I did something wrong?

You should place the coordinate systems you would like to use for robot machining attached to the robot base (attached directly or indirectly).
