Glassdoor says the salary average is based on 11 reports. 5 reports included a bonus averaging $82,701 (and 2 reports included profit sharing averaging $10,345). The question is why only 5 of the 11 reported a bonus; or more specifically, did the others receive bonuses that they didn't report? If Glassdoor assumes that the other six didn't receive bonuses, then the average total pay of $114K makes sense.

    84,315 + 82,701*5/11 + 10,345*2/11 = 123,787

The simple way I see to count these doesn't match the $114K, but it's close enough that I can buy that that's a big part of it. But the question is still whether the assumption (that nobody else received bonuses) is correct. It's plausible that many people fill out only the base salary figure, even if they have other compensation. If everybody gets a bonus, then the $160K figure reported in the other articles could be justified.
