“Approval” task breaks “Column Function” in a section when the tasks are sorted by “None”.
In a section try to have “Approval” tasks mixed with normal tasks, sort by “None”.
Chrome and App. Not browser-related.
Thanks for the report @Rosario_Messina,
I’ve gone ahead and filed a bug. I’ll be in touch here as soon as I have an update!
@Marie I think Product might be on the right track 
These Approval tasks are part of a very unusual but effective workflow; in fact, they contain 31 Subtasks. When the task gets approved, it triggers a rule that creates a project out of it (just to explain at a high level why there are so many Subtasks).
Cheers,
Rosario
Thanks @Rosario_Messina! Our team just confirmed this is product limitation.
With “None” sort applied, Asana aggregate the custom field value from the subtasks, but it limit that aggregation to 30 subtasks and won’t display a value if any task has more than 30 subtasks.
We’re always working toward pushing these limits, but until we can do something for this specific limitation I hope you can trim down this set of subtasks to 30.
I’m moving this thread to the #forum-en:product-feedback for now and will edit the title accordingly
Thank you @Marie for clarifying; it’s good to know about the limitation, this is a pretty rare use case too
