There is some cache that goes on with creating chemicals. In Spyder settings, make sure Enable UMR is on. This should fix the problem. If not, you could restart the Kernel each time you change the module.

I figured it out - it's not from the UMR (it had been enabled), but it's indeed relatedly to cache.

I used <Chemical>.copy to make a new chemical, but I didn't add certain properties for the reference chemical before making the new chemical. Since there's cache, so the system knows that certain slots of the new chemical should be filled based on the reference chemical, but I haven't added those properties yet... I fixed it now, thanks!!!
