Problem with adjacent notes/lengths on different voices

i have a problem with spacing/position of notes with different lengths, and therefore in different voices.
In the example, top staff, beat 3:
voice 1 is Aflat minim and its tail should be going up;
voice 2 is C dotted crotchet and its tail should be going down;
voice 3 is a G quaver and its tail should be going up.
With Musescore's default setting the Voice 1 minim appears later than the Voice 3 quaver as shown in example bar 1.
What is needed is as shown in example bar 2 (where the voice 1 note is now moved up by a tone to clear the clash).
Example bar 3 shows my best attempt to achieve the desired result but it does not look good.
