Thank you for helping me to resolve this issue, @mishig25 

Same as the reason for not applying https://github.com/huggingface/transformers/pull/15601 these tags are there for redirects from other pages so we can't remove them.

The original problem:

I happened to create a new header that was mapped already to an older tag and that's why I am getting both:

https://huggingface.co/docs/transformers/master/main_classes/deepspeed#zero-inference
https://huggingface.co/docs/transformers/master/main_classes/deepspeed#deepspeed-zero-inference

ending up in the same section.

Thank you for catching where the problem came from but I am already resolving it here: https://github.com/huggingface/transformers/pull/15585 by renaming the newly added header to be more distinct.

so closing this one.
