Probably one of two reasons:
1. the root canal procedure is not complete. The pulp/nerve may have been cleaned out but the canals are not filled yet. We usually place a medicament into the canals and close it off with a temporary filling until the finish appointment. This is common if the tooth is badly infected or if it is an emergency and there just isn't time to do it all in one step.
2. there is going to be a post/buildup and crown done as the definitive restoration next. There is no point putting a permanent filling in the root canal treated tooth if it is going to be removed to place a post next month. Teeth that have had root canal treatment, especially back teeth and teeth with big fillings n them, are usually crowned to avoid having them crack later. Root canal treated teeth are weaker than non-treated teeth.
Do either of these situations apply in your case?
