Nottice the first two letters of the second line are touching. Since they didn’t change the shape of the letters, and they didn’t turn one letter into another letter, it was able to be fixed. This was seen on mezuzos that had been previously checked. When people ask me why they have to get there mezuzos checked if they were checked a few years ago, I can show them this and hundreds more like it. Believe me, I see this all the time!
