Fix the pattern
Pattern: I'm running late (for [thing]) / running a bit late
WrongI'm running lately.
RightI'm running late.
It's the adjective 'late', not 'lately'; 'lately' means 'recently'.
PatternI'm running late (for [thing]) / running a bit late
Don't confuse it
'Running late' = behind schedule now; 'I'm late' just states you've arrived late.
