Mother of Rot burrow attack deals too much damage

The Mother of Rot monster that appears in t17 maps and based on the Ryslatha enemy has a variation on the burrow attack RyslathaStandaloneBurrow which deals significant damage. For the equivalent skills on Ryslatha and Gorulis monsters, the skill has a "Deals 75% less damage" modifier. The RyslathaStandaloneBurrow instead has "Deals 0.75% less damage" which is likely a decimal error.
Gorulis standalone version as summoned by Maven and Rituals also has the error.
