Dimension CC is adding a weird line to graphic
I have created in and exported from CorelDRAW 2018, this vector art: https://contattafiles.s3.us-west-1.amazonaws.com/tnt3924/XkBax17syROXhIK/T-Shirt.png
I want to place it on a 3D T-shirt OBJ: https://contattafiles.s3.us-west-1.amazonaws.com/tnt3924/OuP8rkrQLaFxMYe/T-Shirt.obj that I have imported.
Here's my Dimension CC 2019 file: https://contattafiles.s3.us-west-1.amazonaws.com/tnt3924/iaRFxiLTx6l8omL/24FPS.dn
And here's the rendered PSD file: https://contattafiles.s3.us-west-1.amazonaws.com/tnt3924/V-iU57Ccd6BAuZl/24FPS.psd
As you can see, there's no line of colours in the top of the vector art, but, there's one visible when I import the graphic in Dimension CC. It gets rendered also. I can remove it in Photoshop, but, can anyone point out why that is happening?
For those who didn't get what I'm talking about, here's the annotation (the problem area is the one marked within the red bordered box): https://contattafiles.s3.us-west-1.amazonaws.com/tnt3924/EJayPX_g71qKiQ3/Annotation.png
This issue persisted in Dimension CC 2018 also.
