[HELP] Hybrid ignores my selections...?

Sounds like your source is detected as progressive and not interlaced.
(If you had read the [INFO] Infos needed to fix&reproduce bugs,..-sticky and provided proper details, I could have said for sure. Please read the sticky and provide proper details in the future.)

Assuming your source is interlaced, not properly flagged and thus detected as progressive, you should Hybrid know that it is interlaced by overwriting the scan type (Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine Settings->Overwrite input scan type to') to the correct scan type (probably 'top field first') and check your choice through the Vapoursynth Preview.

The 'Auto deinterlace handling' tool-tip:

Deinterlace handling:
Sets what method will be used to deal with non-progressive content, assuming the output isn't marked as interlaced in the encoder.
Hybrid does only deinterlace if:
a. the source is non-progressive
b. the output is not interlaced
So:
- If your source is flagged as interlaced, but in reality is progressive: overwrite the scan type.
- If your source is flagged progressive, but in reality interlaced: overwrite the scan type.
- If your source is progressive and properly flagged, do not worry Hybrid will not try to deinterlace the source.

=> so if your source is not detected as interlaced Hybrid will not try to deinterlace.
