Supply Quality for Country Controlled Public Corps

Hello everyone, this is me again asking.
Is the quality for supplies in Country Controlled Public Corps capped at 180?
I cannot seem to buy supplies for CCPCs at 200.

Maybe you overlooked something.
On the Supplies tab in the Quality column check for:
The box is checked, the radio button next to the number box is filled
and click "Save Order Quantities and Quality". Wait for message Corporation data updated.

The limit is 330.

I'm having the same issue for all state corps. Updated it to 220. It updates (leaving the page and then reopening it). Next game month it's back to 180 again.
