Appears to have problems with latest Dnd 5e game system

I imported Killer Cell from a source that looks like the attached. . The imported stat block ended up having proficiency in str, con and wis (apparently, all the abilities with positive bonuses). Also would appear the importer has all saving throw bonuses off. Here is the resulting stat block: . Finally, it would appear the dumb stat block importer add on does it right:

Here is the raw text that was imported into both:

Killer Cell Medium ooze (cell), unaligned Armor Class 10 (natural armor) Hit Points 22 (4d8 + 4) Speed 20 ft., climb 20 ft., swim 20 ft. STR DEX CON INT WIS CHA 15 (+2) 8 (-1) 13 (+1) 1 (-5) 12 (+1) 1 (-5) Damage Resistances bludgeoning Condition Immunities blinded, charmed, deafened, exhaustion, frightened, prone Senses blindsight 30 ft. (blind beyond this radius), passive Perception 10 Languages — Challenge 1/2 (100 XP) Corrosive Membrane. A creature that touches the cell takes 4 (1d8) acid damage. Tissue Permeation. The killer cell can move through the tarrasque's bodily tissue as if it were difficult terrain. Actions Attach. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d8) acid damage, and the killer cell attaches to the target. While attached, the killer cell doesn't attack. Instead, at the start of each of the killer cell's turns, the target takes 4 (1d8) acid damage. A creature's speed is reduced by 10 feet for each killer cell attached to it. A creature that has its speed reduced to 0 this way is restrained until enough killer cells are detached that is speed would no longer be reduced to 0. The killer cell can detach itself at will (no action). Alternatively, a creature (including the target), can use an action or a bonus action to detach the killer cell.

I am seeing this behavior consistently with every statblock I attempt to import from several different sources.
