If you are experiencing spelling issues in generated reports, please follow the recommended workaround below.
This appears to be a bug in the SAP Crystal Reports SDK affecting the Calibri font type which may cause reports to have spelling errors.
One quick workaround is to change the font used in your reports to something else as this issue appears to be specific to Calibri font type.
If you use the Arial Font-Type or something similar it should resolve the issue. There is no fix available at this time in Crystal Delivery.
