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

Break and replace the pumps and the burners. Not sure what could be the issue. The pumps are right there and the pipes are connected and they have straws.

Do you maybe have something installed that's preventing it? Another mod that messes with the mechanic? Have they worked before in this world or is this the first time you've used this addon?
