Supplementary rules will not work correctly when define an specific business unit

Additional suplementary rules were defined with track control level in which the corresponding business unit was defined (I should point out that the budget control was created for a ledger that only has a single business unit associated with it ). So when the user tries to validate budget in gl for an entry with origin of invoices from ap or ar, it shows an error in the budget validation due to lack of available funds.

For the supplementary rule to work correctly I must remove the business unit from the definition of the supplementary rule itself.

Why in 2023 and 2024 did the supplementary rules work correctly when the business unit was defined and why in 2025 do they no longer work in the same way?
