QSCAN Results intermittent and contain NSA?

Dear Quectel, I would be pleased if you could help with the following. When I run QSCAN I only get results on every 2nd time. I also expected QSCAN to only show 5G SA but I am getting NSA cells.

AT+QNWPREFCFG=“NR5G_DISABLE_MODE”,2 (this is mean’t to disable 5G NSA but has no effect on QSCAN results.

How can I get QSCAN to give me only 5G SA each time?

When I run
AT+QNWPREFCFG= “mode_pref”,NR5G
AT+QNWPREFCFG=“nr5g_band”,1:2:3:5:7:8:12:20:25:28:38:40:41:48:66:71:77:78:79

AT+QSCAN=2,1 (I get result)

+QSCAN: “NR5G”,214,03,426050,241,-,-,-,0,-,-,52,28,13,6,-
+QSCAN: “NR5G”,214,03,152690,59,-,-,-,1,-,-,273,78,200,12,-
+QSCAN: “NR5G”,214,01,154570,141,-,-,-,1,-,-,106,78,34,0,-
+QSCAN: “NR5G”,214,01,648384,174,-,-,-,1,-,-,106,78,32,8,-
