MC and supply flow delay when capturing city

[Baris]

playing with SB whites, sometimes when I capture the city after the battle(enemy retreat to other region or no garison in it) , there is 1 more turn delay to gain military control and supply to flow even there is no other enemy unit in the region. It was generally not like that in prevous age games, I m not sure as it is a bug or wad. 2 examples.

I looked at the Red AI files and it shows that there is no unit in Krasnovodsk, or even nearby.
In Cherepovets there is a red detachment and still retreating(after turn processing) with passive posture after defeated. And it has 0 ZOCl. while Sibwhite has 16 ZOC. But after turn processing tooltip shows that Reds have MC control so supply need 1 more turn to move to the region.
Is it because of no loyalty value.

Edit: Another example is armour trains:
Despite 300 MC tooltip says regions is controlled by Reds.

Another example is playing as Southern whites.
For 2 turns Reds couldnt maintain MC control in region Zernograd. Tooltip show Southern whites have 100% MC and the railroads are open. Reds have militia but have good patrol value.

Edit: in Second turn AI was in passive posture because I uncheck AI, but in first turn it was controlled by Southern whites also.
It seems AI was in passive posture also in first turn , interesting
AI was activated in that turn.

By the way AI is very good about moving small detachments or partisans to cut supply, well done to especially Clovis and the team.
In the previous saves there were a delay about maintaining MC control, Despite the offensive posture.

Contining my own post
This time White army under Fitskhelautov(This one was hard to spell ) decided to siege Tambov. but my fellow comrade Machin in the region and Stalin forces were closing in so he intelligently left the region and marched north.

But in the tooltip it is still showing there is conflict in the ownership about the MC in region Tambov. Because of that I think Reds can not make requisiton from the peasants.? There is no other white forces in the region.

As I know MC is region level, even in Area level his army is outside of Tambov theatre. Red forces was inside the city after turn processing but..
There were 8000 men in the force of Machin including Red fusiliers and artillery.
