99:1 sounds like the wrong antenna output is selected.

This morning I put up a W7FG true ladder line 160M doublet. Upon
testing, the K3 internal atu does great, matches at 1.3:1. But when I
throw the KAP1500 in line, it gets all pissed off, throws up and faults
out. Says SWR is 99:1 !!!
The Antenna: The Apex is at 50'. It is in a inverted Vee config, with
both ends approx 20' off the ground. I'm using 59' of the 600 ohm true
ladder line to a Balun Designs 5KW 4:1 Balun. This is fed with 22' of
Wilson LMR400
Both the K3 internal atu, AND the KPA1500 internal atu get a great match
on 80M, 1.2:1 with no issues.
Honestly, most of the work on 160M is FT8 running 20 watts or less, so
just using the K3 to get a successful match on 160M is fine
I just wonder why the KAP1500 doesn't like the same antenna the K3 likes.
Any ideas here fellers?
thanks and 73
