Yes. A very small load may not behave like the normal compatible load for which a programme is intended. Check the model's guidance for single items and timed options.
Understanding this situation
A short end or uneven finish does not automatically mean the moisture sensing has failed. The garment's own drying limits still apply, so changing to a more intensive programme is not a universal correction.
A useful next step
Choose the documented suitable treatment for that item and avoid adding incompatible textiles simply to fill the drum. If ordinary suitable loads also behave differently, include that wider pattern in the enquiry rather than relying on one tiny load.
