Character Shifting Issue

[aviatorhh]

I am receiving marine weather on 147.3kHz but there seems to be a problem on characterset shifting. See below

Should be (fldigi):

BOTTENSEE (62.0N  19.5E) WT:  2 C
MI  2. 12Z: W        3        0.5 M        //
MI  2. 18Z: W-NW     3        0.5 M        //
DO  3. 00Z: W      2-3         0  M        //
DO  3. 06Z: SW     3-4        0.5 M        //
DO  3. 12Z: W-NW   2-3        0.5 M        //
DO  3. 18Z: NW       5        1.5 M        //
FR  4. 00Z: NW       6   7-8   2  M        //

Is (minimodem --rx -5 -q 50):

BOTTENSEE (62.0N  19.5E) WT:  W C
MI  2. QWZ: W        3        PMT M        //
MI  2. QIZ: W-NW     3        PMT M        //
DO  3. PPZ: W      2-3         P  M        //
DO  3. PYZ: SW     3-4        PMT M        //
DO  3. QWZ: W-NW   2-3        PMT M        //
DO  3. QIZ: NW       5        QMT M        //
FR  4. PPZ: NW       6   UAI   W  M        //

See the difference on the times?
