Tax is not being calculated properly while ordering tickets

[pavnesh-c]

Describe the bug
If we buy paid tickets of more than one type, the tax on orders page shows 0.00 for all tickets. There is probably some calculation issue in tax system.

@mariobehling This porblem is not showing on localsystem.
I think there is some problem in new changes been merges not properly deplying or maybe not deployed to
https://eventyay.com/

bcz the changes made in PR #3820 is also not showing (below ScreenShot).

I think the problem is in deployment and same goes with this PR.
@maze-runnar pls have a look at this problem

Still missing the currencies, e.g. USD, Euro, INR in the tax area, but the calculation works!
