Doing such sharp joggles are very bad practice.
From the photo it look like the cover to reinforcement bars of the column on one side got increased and on other side it got reduce.
The actual column which behave like column is the part which comes under this reinforcement cage, outside of it is only the cover to rebar for protecting it from rusting and also to protect the concrete inside the core area (Durability of structure defined by cover to reinforcement bars).
As from the picture the quantum of problem is unidentified so any suggestion would lead to serious issues.
Best way is to show it to structural consultant and take the procedures from them for doing remedies as such situation might occur in future too, if there is issue in designing of reinforcement bars in structure.
For joggling of reinforcement bars, it should be always done in ratio of 1 inch in 2 feet.
