can't stack more the 5 furnaces

im not sure if there is a glitch but when i try and stack more then 5 electric furnaces in seperate stacks it tells me i can't stack more then 5 total. but i only have 3 in one stack and 2 in another stack and the third it tells me i can't stack more then 5. i put 2 pictures up to better show what i mean. the settings in it say a stack of 5 which i assume is 5 tall since thats what the rest mean since i have large boxes at 4 and can only stack them to 4 high but can stack as many boxes as i want. unless i am completely missing something here
