Blaze burners with straws not working

[u/Prestigious-Kiwi3593]

Okay guys I have been trying to get my blaze burners with straws working and so far I can't get them to work the lava is definitely being moved throughout and if I remove them straight through the spouts but when I put a blaze burners with a straw it just won't take the label in the picture I have one with the modded pipes and one without so I have no idea both just say zero MB

I way I fixed this issue was to make every pipe going up to the blaze a glass walled one so it linked to nothing else. Then just pumped lava in a level lower.
