Can't set custom prices for commodity exchange orders

When trying to order a commodity, whenever I type in a custom number in the price limit field, it automatically reverts to a specific number. This issue occurs even after changing browsers, and I can’t seem to understand why.

Price bands. You can’t place orders outside of them unless you have a PRO subscription and a 45 day old account.

That’s a possible explanation, but I think we got him to check that. The number it kept forcing into the Price Limit field was the Price Average, not anything related to Price Band.
