Entropy calculation on website doesn't match tool

[dgrant]

The following config says 61 bits with full-knowledge on https://xkpasswd.net/ but when I run locally I get WARNING - Crypt::HSXKPasswd::_update_entropystats_cache(): for attacks assuming full knowledge, the combination of the loaded config and dictionary produces an entropy of 33bits, below the minimum recommended 52bits at /usr/local/bin/hsxkpasswd line 448

{
"num_words": 3,
"word_length_min": 4,
"word_length_max": 8,
"case_transform": "RANDOM",
"separator_character": "-",
"padding_digits_before": 0,
"padding_digits_after": 0,
"padding_type": "NONE"
}

Seems to be if you choose case_transform: RANDOM, you get double the entropy, when you should really only get num_words more bits of entropy. XKCD config should be 44 bits, not 80 bits.
