This happens because only certain versions are accepted:

CECE/src/io/tide/tide/src/tide_cf_detection_mod.F90

Lines 218 to 221 in 602e9ec

	if (index(str_val(1:att_len), 'CF-1.6') > 0 .or. &
	index(str_val(1:att_len), 'CF-1.7') > 0 .or. &
	index(str_val(1:att_len), 'CF-1.8') > 0 .or. &
	index(str_val(1:att_len), 'CF-1.9') > 0) then

whereas really I imagine any CF-1.x should be fine.
