Correcting audio reverb and echo

It is amazing what 24 hours can do. I have aligned the two tracks with the video and it works perfectly. I have no idea why it went wild yesterday...me?....or a gremlin? I also improved the audio using a little EQ to frequency scan, Adaptive EQ, Voice Isolation to remove echo, Compressor and Noise Gate to lift the sound depth. This same incidence happened last year as well. I think Apple needs to explain how to use all its Logic and audio tools listed in FCP. There seems to be a shortage of "How Too" videos on Youtube about these resources. There are a few but not many. The Apple manual of 140 pages does not provide many 'how to' examples.

Thank you all for your comments. I believe the audio corrections for allowing both voice tracks to sync clearly with the video is not a simple problem. The issue is interference and echo across two mics. I have routinely tried all the quick FCP tools like Voice Isolation without success. I will do some more research but luckily I have a third track in reserve. Thanks again.
