No, Frame 1 in the Time Finder is valid because it is referring to the IV frame - IVs and PID/nature are generated seperately. The IV frame should be left at 1 because advancing it is a pain in the arse.
If you have done it the same way as with Reshiram, then you have been lucky, because you got your nature on the initial frame.
The PID frame can be advanced easily by listening to a Chatot's custom chatter - or by the time consuming saving, when you do not have Chatots. You start at whatever the RNG Reporter is telling you and you advance everytime you do something we have mentioned earlier. Unfortunately, it does not make it any easier, because you keep getting a Bold nature, which are on 80, 87, 120, 234. If those are NOT Bold non-synch frames in your RNG Reporter, then you simply have given us the wrong seed, probably by mistyping (still unlikely, because you are able to copy/paste the seed).
Anyway, let's recap: You advance the PID frame by listening to a custom chatter of a Chatot or by saving. Do not walk, it makes matters worse.
