Craft caches tend to mess up sometimes. Clear it manually with this SQL.
You can manually clear all of the Craft 2 cache with the following SQL.
We assume your Craft2 database table prefix is craft_..
delete FROM craft_templatecacheelements where cacheId>0;
delete FROM craft_templatecachecriteria where id>0;
delete FROM craft_templatecaches where id>0;
Craft 3 differs a little:
START TRANSACTION;
delete FROM craft_templatecacheelements where cacheId>0;
delete FROM craft_templatecachequeries where cacheId>0;
delete FROM craft_templatecaches where id>0;
COMMIT;
