Creality print 6.3 slow speed

I have an issue with CP starting with ver 6.3. All prints are being printed twice slower than on 6.1 and 6.2 before (settings and filament update). Also wall generator set on classic as default, which is strange.
Any solution with speed? I’ve checked everything 6.1 vs 6.3 and all parameters seems the same but speed still twice slower.

Found problem somehow jerk settings are significantly decreased in Creality pint 6.3. Changing them to 6,2 version values brings speed back.
