Post From: Not able to click BUY/SELL on execution window

This problem suddenly started today and is only for ES, not NQ

If I click an order on the DOM , which is a limit order, I can get filled

But when I hit BUY or SELL on the execution platform nothing happens

It's not a size issue as I whittled it down to 1 MES and it's still not executing

PLease see image attached, the bottom DOM is working but when I hit BUY/SELL when I want to place a market order, on the top execution window, there is no response from Sierra.
