With TOAD 16.3 Beta 16.3.230.2084  
When I modify the size of a datafile (Auto Extend On) of a tablespace, after OK, the "Maximum size" became UNLIMITED.

Thank you.

I see what's happening here.

See how the max size units dropdown is disabled in my screen shot below? That's when it happens.  
If you manually re-type the max size (3 in my case), then the max size units will become enabled, and then it will work as expected.

You shouldn't _have_ to do that, of course. This is a bug and I will fix it for the next version.
