Hey, sorry for the inconvenience! We checked everything out and it seems like you marked some fields as temporary solution - its all the bluey ones. The properly solved field has different colors - such as red/pink/violet etc. To solve the level, you need to change the temporary marked fields (blue ones) to normal ones and the main indication is the field color.
You can also change all temporary marks into normal ones with the right click menu. We'll also dive deeper into Hexologic and all the smaller issues players might be having, right after our new game announcement next month :)

Thanks!
