Your boiler is simply performing a routine safety cycle where it keeps the pump running for a short time to move leftover heat away from the system, and this is completely normal behavior.

Monitor it

This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
