if you read the paper
it gives an impressive list of MOD successes for dynamics on the galactic scale. ( In some ways you expect it to, as it was tailored to galaxy rotation anomalies that ΛCDM cannot explain. But seems to be covering quite a range of effects/observations on this scale ). The paper shows that it MOND isn't working on a much smaller scale of the larger (i.e. weakly coupled) binary star systems, whilst ΛCDM is.
So, you seem to be mis-quoting the paper, which concludes "While our results falsify MOND as currently understood, given the many problems for ΛCDM discussed in that work, our results cannot be used to argue that it is the correct model either − both models are clearly incomplete".
ΛCDM being the established non-MOND version of general relativity, inclusive of its Newtonian limit.
