3 second delay in updating the price.

Good afternoon,

1) We have the problem that when selecting a block the delay in updating the price depending on the quantity. Is this how it works or is this delay due to some type of error?

2) The discount percentage that appears after the price can be relocated, for example, to a separate line, how can we do this?

3) The last problem that is arising is that the price is not changed when increasing or decreasing the quantity of items after selecting a price block.
