Spruce trees won't grow in tree farm Minecraft Java Edition 1.16.1 {Simple Tree Farm by Ilmango}

I built the Simple Tree farm by  Ilmango which is supposed to grow 4 different tree types. They are Oak, Spruce, Jungle, and Birch I have built in previous versions of Minecraft Java Edition and it always worked but in 1.16.1 whenever I place a Spruce Sapling it doesn't grow and all the other ones do grow immediately.  I left a sapling there for and entire stack of bone meal to no avail.  I enclosed a screenshot so you can see the blocks that are around the sapling just in case that is what is causing the issue.  Thank you for your time and consideration concerning this matter.
