Light remains after snow/iron golden summoned using a Jack O Lantern and iron blocks.

This issue occurs whenever I create a snow/iron golem using a Jack O Lantern instead of regular pumpkins. The light cannot be removed by any known means to me, even with commands I could not do it.(Referring to the command Light_Block which allows me to create and remove light).  Please fix this issue as now There are random areas which are not when I don't want them to be lit.(Note the Light_Block 10 in my inventory is for me to test if I can override the light, the light is not from the light block but the Jack O Lantern that doesn't exist anymore.)
