System.ArgumentOutOfRangeException when converting doc to html

there is an error pasted below when converting attached document to html (tested latest aspose 18.7).
Error is when equations are set to Images and is gone when I set MathML as equations format.

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: Cannot add column at this index
