I'm importing the logs from the 0.9.x installations (yeah, I'm late) into 1.2.1 on Debian Sid. In one log I have four frequency errors I cannot resolve. I noticed that all four of the frequencies are in the upper part of the 2m band which is legal here in the USA. I went into the preferences adjusted the band limits for Region 2, USA. I tried the import of the four errors (after edting out the ERROR: lines) and received rejection of all four records.

Looking at the exported ADIF, initially the Band tag was set to 0 and no Band value was present. So I set it to '2' and added 2m per the ADIF spec. Here is a fragment:

<MODE:2>FM<FREQ:6>147.06<BAND:2>2m

and I get:

ERROR: Wrong frequency:147.06

which is out of range for Region 1, the program default. It seems as though manually setting the 2m limit to 144 and 148 had no effect.
