I think this is a repeat of what happened last time (see link).

The orange numbers which indicate that a new release have appeared on my reading list without a corresponding release appearing. Last time, I think it had been found to be that a no-name group had made a release which had been taken down because it didn’t meet the requirements. Anyway, now the orange number next to Mahou Sensei Negima read (c.213), not the ones I can set, the ones which are updated by the site when a new release comes out. Anyway, I hope it’s another quick fix.
