I can't read the angle in the screen shot, for some reason the image is very low resolution for me, but I have run into this, or something similar before. It didn't seem to matter what number I put in Infill Line Direction and Cura seemed to just ignore it. When I had a sequence of different line directions, I had previously seen it end up in square brackets for top and bottom line direction, like [0,30,60], and this always worked, so I tried it a sequence of one direction, and that has been reliable for lines, zigzag, grid, and triangle. It might work with the other patterns, too.
Long story short - the fix for me was to put the number of degrees for the rotation within square brackets. For example:
15
... generates the same result as leaving the direction blank, but:
[15]
...rotated the pattern direction by 15 degrees.
I hope this workaround works for you!
