Problem with the base at the control point Tyulyovedene PC

After leaving the game, my base at this control point disappeared and the enemy’s base took its place. But this base cannot be destroyed. When I approach the command center of an enemy base, I have the options (capture control point) , (abandon base). But when both options are pressed, nothing happens.

When creating a new base at another checkpoint, the building limit considers that I already have a base somewhere, because of this I have a limit of 8 walls.
It happened in single player. After turning off my comrades with whom we defended the base.
