Good that the pattern repeated but still strange that the 10kHz programming turns over at xxx.528!
The observations still support the divider is bad.

There are no diodes to give trouble here - see schematic snippet.

I think the socket should be OK since the TC9122 is only working at about 4MHz. I'm not sure I would go with it long term but for fault finding probably OK.
Make sure it is the turned pin type - the others cause more faults than they are worth!!
