bitx20 3C SBL - Bandpass filter inductor issue


I've got this kit I've had around for 4 years and it is mostly working though there is an issue with the three inductors not "adjusting." The tuning plugs move just fine, but I have to put an absurd amount of pressure on them, then they start to pass RF. I've actually picked up stations after fussing with them, but I would like to know if anyone else had a similar issue with the bandpass filter and any guidance to correcting the lack of tunability.
