I believe you must be using 6.5 on your local which might not be an inplace upgrade.
@troubleshooter3 In comments you have mentioned that its a migration from aem6.3 to 6.5. If so it is, can you please elaborate how you have created CFs in aem6.3. Using Simple Fragment as OOTB template, or you have used custom CF template or You used CFModels, which were introduced during AEM 6.3.
If you have CFs created out of CF Templates, which was prevalent until AEM6.3, then you will to write a migration utility for these CFS.
If you don't have existing CFs to be migrated, and just want to see CFMs enabled after inplace upgrade, probably you will have to install few service packs on top of 6.3 before you upgrade it to 6.5. Please explore from below links:
