It's not what you think

Shouts getting stuck is an old thing and I don't actually remember what causes it or fixes it, but I haven't had it in my modded games for a long time
Try installing the lesser power internal cooldown remover, that might do it, also it's nice because if your shout cd is low enough you can chain them without the baseline wait, which is especially annoying with slow time
