\"AutoCorrect\" ships (Stellaris)

At the end of the game to face bug where the game incorrectly perceives the drawing of the ship. Explain. I have corvettes and cruisers several drawings, but when I create any of the corvettes such as the game interprets them as missile corvettes, therefore, believes that the initial of the corvettes is not enough and in the amplification (recovery) fleet adds extra ships, and in the modification reworks them into a missile. Might be related to a mod, don't know. If need be, throw a list of possible mods.
