Don't use Kraken Custom Orders

I know that Kraken is a favorite of many of you and although I like Kraken myself I need to complain about the latest feature they introduced which is Custom Orders. I recently tried it for the first time and a few days ago I set up a Custom Order for ETH.
My custom order was set to trigger at $1898. Today the price went down to ~$1860, my order got triggered but the price Kraken decided to realize my order was $2205, which is ~$300 ABOVE my target price. If this is how Custom Orders are supposed to work then better not use it.
Beware whenever you set a Custom Order that this is how it works and you have no guarantee if it triggers above your target price.

my target price was 1898 but it triggered at 2205
