I have 2 store views, one for normal customers (product prices including tax) and one for wholesale customers (product prices excluding tax). See images for reference.
Normal Store View (product prices including tax):
Wholesale Store View (product prices excluding tax):
And additionally, I have special prices for the customer group Wholesale in some products like this:
When I log in with a wholesale account for example in the store view EN (prices including tax), I see the correct special prices.
But when in the same session I change the store view, I lose the special prices and I only see the normal customer prices:
If I log in with a wholesale account but now in the store view Wholesale (prices excluding tax), I see the correct special prices too:
But when in the same session I change the store view, I lose the special prices and I only see the normal customer prices again:

UPDATE 1
The entity_id of this product is 2726, the customer_group_id is "2" (Wholesale group) and this is the result of Query:
SELECT * FROM catalog_product_index_price WHERE entity_id = 2726;
UPDATE 2
