The bobbin tension sounds too loose. This will help if you have a bobbin case and not a drop in bobbin. Let me know if you have a drop in bobbin:
Setting bobbin case tension:
Put wound bobbin in bobbin case. Thread it in case. Hold the thread and carefully let go of the case only holding bobbin thread. The case should NOT move. Quickly let your hand drop 2-3 inches to let the bobbin case free fall for 2-3 inches, the bobbin case should move slightly then stop. It moves because it let’s a little thread off the bobbin. It should then stop .5"- 2" of thread should release. If so, your bobbin case tension is right. If it’s right then begin to look at your top thread tension. Always Always start with a properly adjusted bobbin case, then adjust your top tension accordingly.

When putting your shirring elastic on the bobbin, don't thread the elastic through the bobbin holder,adjust the stitch length longer,and loosen the tension, other wise if you want to put it through the bobbin holder you have to loosen the tension screw on the bobbin holder, and then you have to adjust it back for ordinary sewing,

Is there a stitch width setting and has to be set to a number greater than zero?

SOURCE: shark 384 - how can i get a straight stitch?

with the Shark Euro-Pro X machine, you need to bring the stitch width to zero it's the nob on top of the machine the manual states not to use it wider then 3 with the double needle cause it can break the needle. but either stitch selection "A" or "S" will give straight stitching with width at zero.
