Invoiced expense that is reimbursed is showing up in Taxable income for GST report but not in Trial balance

I invoiced a client for expenses that were reimbursed.  It appears to be recorded correctly with the expenses being credited (and it does not show up in income when I look at my trial balance for end of year) however, when I do the GST report, the total amount of reimbursements is showing up in income.  The two income totals do not match and I can't figure out why and how to fix this.  I'm still in trial period and not sure if I want to make the move or not... running out of time so a quick response from anyone would be helpful.
