Fix:

Edit the file Sid Meier's Civilization 6\Base\Assets\UI\Panels\ProductionPanel.lua

Search for:

for i, item in ipairs(unitData) do

after

else
unitListing = unitList["unitListIM"]:GetInstance();
end

add these codes:

if item.Corps or item.Army then
    if unitListing.CorpsArmyDropdownArea == nil then
        item.Corps = false
        item.Army = false
    end
end

For me, it's works. Once you finish UNIT_TRAIN_NEED_MILITARY_ACADEMY, you may get the issue. Because your unit not support Corps or Army, so disable them.
