The best choice is to delete the 8 items with low correlation and retain the other 17 items. The low item-to-total correlations suggest that these 8 items are not measuring the same construct as the rest of the items in the instrument. Removing them would increase the homogeneity of the instrument and improve its validity and reliability. Retaining the other 17 items ensures that the construct being measured is still adequately represented in the instrument.
