How did you delete them? Depending on the OS, it's not uncommon for files to be sent to a hidden trash directory, rather than being outright removed. If you did this on a PC, try reconnecting the SD to it, and empty the trash bin. Another possibility is that it's showing signs of corruption, and you can test for this with this tool.

No problem! If you're on a POSIX system, like macOS or Linux, this is pretty common. Just be mindful to empty the trash before ejecting storage, and it'll clean everything up.
