Looks like the charts, at least for https://bfxdata.com/swapstats/usd (maybe others, I haven't checked) are having some issues with the FRR.

The sidebar has the correct number listed under "FRR (% day)" but the bottom chart has the vertical line stuck at 0.05161, and has had it stuck there for some time.

I think the same stuck variable might also have been affecting the top chart, and the "Last opened Margin Funding" list. Have seen funding getting recorded in the list and on the chart at exactly 0.05161% when the actual FRR was substantially lower and so far as I can tell from the Bitfinex interface no funding was actually taken at that rate, so my suspicion is that "funding taken at FRR" was being translated into "taken at 0.05161%".
