Order ID changed... but...

Hello I changed my ORDER ID to 22222. This works great... but! Somehow Hikashop makes something strange out of it. What is going wrong?

See my screenshot, the last 2 orders... they started with 22222 but somehow this is the result...

B2W2A2E22 is not the order ID but the order number.
The order id is on the right end of that listing.
If you want to change the order number format for new orders, you'll have to change the "order number format" option of the configuration as explained here:

Thanks... works!
