Problem with some Switch NSP updates (South Park + Hollow Knight) ...

[18Phoenix]

Hi,
till now everything runs fine with my SX Pro and the new SX OS 1.6 and a 200GB microsd as install-target.
But I can't use the following 2 updates:

• South Park TFBH [UPD][01008F2005154000][v327680]

• Hollow Knight [UPD][0100633007d48800][v131072]

I've noticed that the XCI-Explorer (1.4.2) shows only the size and nothing else, no title ID or name or icon, nothing.
That doesn't happen with ALL other update files I have and all others work fine.
Do these updates not work with SX or are they corrupt somehow or is the XCI-Explorer working incorrect ?
So where is the problem ? Someone can help ?
