Apple's iOS 7 might be causing some extra headaches for schools, according to a new report.

Several school superintendents have reported to All Things Digital on Thursday that after updating to iOS 7, the iPads they were supervising have been stripped of their filters, allowing students to potentially access inappropriate content.

According to the superintendents, the iPads they've deployed throughout their school districts were outfitted with supervision profiles that limit what students can access from the tablets. The profiles were filtering out unwanted content in iOS 6, but were totally lost in iOS 7. The schools were forced to wipe the devices clean and start anew.

Apple's iOS 7 launched last month. Just a week after its launch, Apple reported that the operating system was running on 200 million iOS devices worldwide. According to AllThingsD, the operating system was installed on "thousands" of tablets in schools.

Apple has acknowledged the bug, saying that it's also seeing it among business users who are presumably using remote device management features. The company has promised a fix for later this month.
