Welcome to TFP! With a CYA that high (if the test was accurate), your FC is not only okay but needed. See the FC/CYA Levels on how FC and CYA should be balanced together.
How are you testing your water? Also be sure to update your signature with all f your pool and equipment info, to include your test kit, which will help us better answer your questions.
