Technically similar string but evaluated differently

[goodudetheboy]

I tried on these two (sort of) similar OH strings on the evaluator, but the result comes out differently:
Mo-Su 16:00-18:00, 19:00-21:00; Mo-Su 17:00-20:00 unknown

and
16:00-18:00, 19:00-21:00; 17:00-20:00 unknown

In the Features section, I read that If a rule's date condition overlap with previous rule, it overrides (as opposed to extends) the previous rule., but shouldn't the rules with unspecified dates also override?

I think you are on to something. Looks like the library does not behave according to the specification.

This is still an issue, using 08:00-18:00; We 08:00-12:00 gives completely other results as We 08:00-12:00; 08:00-18:00...
Using one schedule does state that at 13:00 state is open, using the other string the state is closed.
