I was able to reproduce the issue.  When I repacked these using the
Rev. 22 MAGSAV, the install worked correctly.  Here's the repacked tape
set:

Since the emulator doesn't support limiting the size of a tape, I don't
have a way to produce these things spanned across virtual reels.  That
means you'll have to adjust the instructions a little.  You need to read
the saves in this order:

BT
U1
U2
V1
IC

You won't have a "next reel" prompt in the middle.  Each restore will be
logical tape 1.
