Excellent suggestions for a next diagnosis step!!
You simply CANNOT use any preamp in your situation. The weak VHF stations can easily be trampled by the strong 2nd harmonics of 2, maybe even 3 local FM signals. Trying the FM filter is a good idea also. You may even need something stronger, but this is an easy way to test with something available locally.
If amplification is truly needed, I recommend the Channel Master 3414 which is extremely tolerant of blistering VHF & UHF signals & will deliver an even, robust signal up to 4 splits with minimal dynamic range compression.
