If the amount of compensation claimed be disallowed, but another amount awarded, the compensation judgment shall be a lien to the extent of the award, as of the date of filing the petition with the prothonotary, with the same effect as to other liens and the same disability to issue execution thereon as if the compensation claimed had been allowed. In such cases the prothonotary shall make such modification of the record as shall be appropriate.
