clear before scan

[qatar2022]

Dear all
with vu+dou 4kse and blackhole and the setup tuner is simple mode Diseqc a/b (a=26.0E Badrsat & b=7.0w Nilesat) when I try to search one satellite a to add only 6 channels on manual scan I disable (network scan, clear before scan and only free scan) when I press scan and after finish I notes that all channels that I have it before was deleted and I found only the 6 channel the I searched recently is that bug or do I miss something
with regards

You selected clear before scan, so it removes the current channels.

If you want to keep the current channels, then you do not clear the channels.

If you only want to search 1 transponder and not the complete satellite, do not use Network scan either.
