I have created a few custom shapes in Lucidchart by designing them and then exporting the document as an "SVG with transparent background". The document is exported and looks perfectly fine but once I upload it into my custom shapes library some of the outlines will be lost. It has only happened with two shapes and none of my other shapes have had that issue. I don't know what is different or what went wrong with the two designs. 

See the attached images for the design vs what is created when shape is imported.
