In OpenElis, when we try to add sample for a patient, we are getting "The appropriate sample for each test must selected." whereas the expected message should be "Save Successful"

Steps to reproduce:
1. Login to OpenElis with 0.93 version
2. Navigate to Sample -> Add Sample.
3. Search for patient with Id : GAN203006
4. Choose any sample type (ex. Pericardial Fluid) and then click Add Sample.
5. Select any of the available tests
6. Fill in Order details.
7. Click on Save.

Some findings:
Seems like some XML parsing exception is popping up. Attaching the screenshots for reference.
