Library subsystem that contains a stateflow chart doesn't apper in the library browser any more!

Hi everyone,

I try to build a custom library (for example myLib). In this library, there is a subsystem (for example Subsystem1) containing a stateflow chart. After refreshing the library browser and expanding myLib, Subsystem1 doesn't appear.

Only when I delete this stateflow chart, Subsystem1 will be displayed again. Strange!

My Matlab version is R2017b.

Is there anyone who can help me to solve this problem?

Thank you!

I also found that this problem occurs if the library subsystem contains a MATLAB function block.

However, if I add this library to the library browser in MATLAB R2017a, the problem doesn't exist! Is it a bug of MATLAB?
