Cannot extract bmp file to word or PDF

While trying to extract my bpm file to Word or PDF, I receive the following error message:” Object reference not set to an instance of an object"
And while publishing to web, I also receive the following error message.
"The 'Insert' start tag on line 3 does not match the end tag of 'LI'. Line 3, position 1170"
When I started using the Table extended attribute, these errors began to happen.
I am using the Version 1.6.1 of the modeler. Can these errors be fixed?
