Duration field not filled automatically

Hello,

I admit I have this issue for at least a few months now, but it’s more of an annoyance than a plugin breaker. Usually, when I saved a draft of a podcast type post or published it, “Duration” field in “Podcast Episode Details” under post’s content was filled automatically (if episode’s URL was correct). It still works for “File size”, though.

Is it an issue on my side, or a known bug? It would be great to make it work again.

Thank you in advance
