Tax code total allowance shortfall

I used to have 2 tax codes for 3 income streams. An occupational pension with 575L and a main job plus an zero hours bank shift job (with the same employer) with an aggregated tax code of 681T. After changing my main job, my tax codes were changed today and are now 181LX for my pension, 451TX for my main job and 230T for my bank shift job. The tax free allowances add up to £8620. Does anyone know if this is correct and if it will revert to £12570 at any point? Many thanks Does anyone know if this is correct
