Thanks for reporting this.
The plate-solving system does produce a significant number of false positives, unfortunately. The reporting system was introduced last weekend as the easiest way to remedy this, and when I notice false positives myself, I often flag them right away. However, there’s clearly some outstanding permissions issue that my testing didn’t pick up.
I won’t be able to look into this until very late tonight, but I’ll aim to get this fixed for you tomorrow.
