You said you had 16299.214 on Feb. 4th. and it was KB4058258 that raised the build number to .214.
Cumulative Update KB4058258 Windows 10 v1709 Build 16299.214 - Jan. 31
...so it appears that you did have it at one time. Unless you have done a clean install or (as I did) an in-place upgrade repair since then, you will still have the some remnants of KB4058258 on the system. It is this that seems to be responsible for DISM being unable to reclaim that package. It appear to be a package that was part of KB4058258.
