Can't release version (an update). To manually release this app as a pre-order.

I want to release my version, how it was always with button Release version, but now appears - "To manually release this app as a pre-order, go to Pricing and Availability."
App already has existing live versions, also, of course, I don't have this section, as it is not a first release version.

Please help me on that, is it a bug in App Store Connect?
Apple, please, make sure that manually release button is correctly working (appears). I only managed to impose a button, when it appears less than 1sec.
same here is there any fix for this
edit :
i disable pre order and everythings work now
