The items can have different care limits and contamination histories despite both being used for cleaning. A coated cloth may not tolerate the same wash-and-dry treatment as a plain towel.
Understanding this situation
Check each product's instructions and any substances it has absorbed. The programme cannot identify a chemical residue or an incompatible coating for you, and a high-temperature combined cycle is not a universal cleaning solution.
A useful next step
Create compatible loads and use appropriate handling for contaminated materials. Keep uncertain cloths out of heated drying. If a coating sheds or an unusual smell appears, stop further use and report the actual contents rather than labelling it ordinary lint.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
