Taxes bug

Hello. I have reported this bug multiple times by email. Two years have passed and nothing has been resolved, so I am posting it here.
When the “7-day trial” is enabled, prices are displayed including sales tax, even though “tax-inclusive pricing” is disabled in the settings. If I disable the “7-day trial”, prices are displayed correctly excluding tax.
Customers do eventually pay price + tax, which is correct, but the issue is that tax is shown as included upfront, whereas I want taxes to be shown separately, not included in the displayed price.
