Set camera to movable

So i opened my project and i got this massage when i pressed play:

‘Mobility of /Game/UEDPIE_0_Level1st.Level1st:PersistentLevel.MainFirstPersonCharacter_C_0 : FirstPersonCamera has to be ‘Movable’ if you’d like to move.’

So i opened my character’s blueprint and i clicked on the camera to change it to movable but: No movable option, no stationary, no static. - Album on Imgur

Does anyone know what is going on? Is it a bug?
