Or Mashima was just lazy with the whole time paradox thing this time around. Could be anything tbh.

Remember, while the Dragons themselves were removed, their presence in the timeline was not. Instead it directly integrated into the main timeline(i.e. Atlas Flame's memories and also Zirconis's title) It could be linked to the first generation time jump as well of course. Since the timeline is still affected by the previous time jump, it cannot fix itself properly.

If what you say is proven true, then both time jumps will be wiped from a particular reality plane. Existence of Dragons would have faded even more, assuming Acnologia himself was or was not affected by the time jumps. People would forget about the actions of Natsu and in turn most of the things FT had accomplished. That all leads to an even more messed up future though and I doubt Mashima wants to go anywhere near that.

It depends on which kind of world line it is going for as well. In more articulate series, revising a time jump includes wiping any and all data related to the anomaly. In more chaotic ones, one world line is permanently affected by all the time jumps so revision has very little impact on the overall path. The decision to close/destroy the second gate would be counterproductive because it would also affect the whole point of the time jumps at all ->Acnologia

Maybe it will get even more convoluted and show that Acnologia exists only because of the time jumps messing up the history of Dragons. Who knows?
