The last operational GPS satellite to use PRN26 was SVN26, which was removed from the active GPS constellation on day-of-year 006 (6 January 2015). It was supposed to have been boosted out of the GPS orbit ring at 19:10 UTC on 12 January. But perhaps there were subsequent manoeuvrings. As typically happens when satellite orbits are significantly adjusted, JspOC loses track of them for a while. Another example is Galileo 6, whose orbit is being adjusted to make the satellite usable after initial injection into the wrong orbit. It's orbit hasn't been recovered yet by JSpOC although ESA knows where it is.
