Smartsheet Jira integration not pulling all items in Query.

Hi, I have a query that is looking for all Stories in about 25 epics. In addition I have pulling the 25 Epics via there IDs. I am only getting a some of the rows to come to Smartsheet. I am only pulling to SmartSheet nothing is pushing back.

At times I get the following Error "Unable to parse ''{0}'' as a datetime."

Can you help?
