As Nick pointed out the algorithms that you purchased remain in your account. If you buy a standard, it will become a max if you purchased 20 algorithms. The algorithms included in the standard don’t count towards the 20 that you need. If you buy a core, you need to purchase an additional 30 algorithms. You say you’ve bought all the algorithms but it!s not clear to me how many you actually purchased separately from the algorithms that were in your original standard. This web page attempts to lay this out.
