The damage is right. All STR-based weapons max out on their regular damage at the same level as strength of the character, see SWD p. 48 under "Minimum strength", so a Str+d6 weapon in the hands of a d4 Str character should, correctly, only do d4+d4, not d4+d6.

As for the min strength requirement, it looks like HL interprets the Strength Die field as doubling for min strength if it isn't otherwise set, for some reason. You might do like the Telescopic Club does and just put it into the Special Damage field instead.

Edit: Actually I see now why HL does it that way, in the same section of SWD I mention above it states "If a weapon has a damage listed as Str+d8_2, for instance, then the minimum Strength the wielder must have is d8." So the damage die, by RAW, implies a Minimum Strength even if one isn't, otherwise, listed. So the appropriate workaround would, indeed, be to list any damage that ignores that rule as Special Damage instead (and the description should probably note that it ignores that requirement as well.)
