Missing data items in a begin_repeat

Hi community. Has anyone experienced a similar issue? If yes, how did you resolve it?

I exported my data, but noticed that some values from a calculate question (used to compute labels of selected item(s) in a select_multiple; for a begin_repeat) are missing from the exported file. However, these values are visible in the Data Table view. Kindly refer to the attached screenshots for reference.
