First:
Finesses never seem to make. Often it's worst case distributions. In normal bridge life, even with computer generated hands in club tourneys or regional tourneys it's not like in robot BBO. Often I do not even try to make a finesse, e.g. entering dummy with some difficulty for making a finesse. It is better probability to just play the ace and play to JQ in dummy. King is most probably left of me anyhow.
This is just your imagination, maybe over a small sample size. If you carefully kept track, over a large # of tournaments, not skipping counting of any hands, I guarantee you that you will find that half of your 50% finesses will work. Besides, in a duplicate tournament, if the finesse is off for you, it's off for everyone else also, so it shouldn't hurt your result (unless there is some superior line that avoids the finesse).

Second:
GIB explanations are often just wrong. Especially concerning the length of the bid suit. But also regarding the number of cards GIB thinks he has.
The screenshot which I attach shows GIB thinks he is holding (at least) 15 cards!
There are tons of bugs and omissions in the GIB bidding database that cause bad bids, and bad definitions for bids, bad explanations. Especially for rarer auctions, it falls back on what rules it has so sometimes explanations combine into something nonsensical. If you post the problematic auctions here, BBO personnel will notice them, and slowly fix at least some of them.
Instead of posting screenshots, try finding the options button, there is an "export handviewer link" or something similar, and just copy/paste the URL. Or better yet, follow the instructions here:

That way insures we see the whole auction and possible bugs in earlier bids in the sequence as well.
