In every case in which one claim is filed against two or more buildings, mining claims or other improvements owned by the same person, the person filing such claim must at the same time designate the amount due to him on each of such buildings, mining claims or other improvements, otherwise the lien of such claim is postponed to other liens. The lien of such claimant does not extend beyond the amount designated as against other creditors having liens, by judgment, mortgage or otherwise, upon either of such buildings or other improvements, or upon the land upon which the same are situated.
