I uploaded exact same Qrda1 content as we got from Cypress for Colorectal Cancer Screening measure. It passed, but showing some warning (screen-shot attached).

Value with string type found. When possible, it's best practice to use a coded value or scalar. Located in element with QRDA type: LaboratoryTestPerformed and id: 1.3.6.1.4.1.115(root), 4609e2ca-55f4-4212-a785-4f2dc0bbaf42(extension)

Please provide necessary solution to this warning to resolve this asap.
