After clearing all Nightwave acts, how do you replay previous weeks?

[Exodess]

I've cleared all my weekly acts for Week 2 on Nightwave, but I cannot find an option to run Week 1. 

Granted, I also cleared Week 1's acts, but the missing replay option is setting off some red flags for me and I'd like to know where I can locate it down the road. I've searched the wiki and Google, and asked in-game Region chat -- but nobody seems to have even posed this question or has an answer for it. Is the answer just that obvious and I'm missing it?

As far as I know, the old missions come up automatically once you finish the current week's. I have always finished previous weeks, so I haven't seen it myself, but that's what I was old happens.

they only show up if you haven't completed them. IF you did all of last weeks, and this weeks, you can't do last weeks again. its not designed for you to get farthur ahead but rather to catch up when you're behind

Cool, thanks. I wasn't aware there was automation involved. :)
