The current 'ublock filters' contains a rule for spiegel.de that disabled all cosmetic filters and the possiblity to pickup an element.
This issue occurs only on spiegel.de.
The rule that causes the issue can be found in line 4920:
@@||spiegel.de^$shide
As soon as this rule was removed ublock works as expected.
Without that filter you'll get anti adblocking stuff
But if this filter is enabled, cosmetic filters and the pickup functionality are completely disabled :-|
For example I hide the complete header (via the pickup feature)
If rule @@||spiegel.de^$shide is disabled:

If rule @@||spiegel.de^$shide is enabled:

Yes, it's a uBO bug, hasn't been fixed yet.
Hmm, cannot be fixed (in this case), shide will disable any filter created by the picker
You can add
||spiegel.de^$shide,important
spiegel.de#@#.asset-affiliatebox
spiegel.de#@#.nativead
spiegel.de#@#.nativead + .headline-date
spiegel.de#@#a[href^="http://paid.outbrain.com/network/redir?"]
spiegel.de#@#a[href^="https://paid.outbrain.com/network/redir?"]
spiegel.de#@#a[data-nvp*="'trafficUrl':'https://paid.outbrain.com/network/redir?"]
spiegel.de#@#a[onmousedown^="this.href='https://paid.outbrain.com/network/redir?"]
spiegel.de#@#a[onmousedown^="this.href='http://paid.outbrain.com/network/redir?"]
to your filter list. The picker will work and you should not see any anti adblock message.
Just wanted to confirm that the solution by okiehsch works for me. Is there a reason why the filter list cannot be adjusted to reflect these changes?
done
