This is how the world looked after creating it and destroying some blocks:

Yes this is a known issue, I forgot to add it so thank you for reminding me. When a chunk is first generated it has to calculate the light values. The way that it does that is it goes to each row (left to right) calculating the highest tile in the chunk and then calculating the light value only downwards. Because those two tiles were the highest tiles in that row, it started the light value at its highest amount and then went downwards. It doesn't take into account the height of neighboring tiles which is what needs to be done.
