Missing meta-data after recipe update

@conda-forge/staged-recipes

Hi,

I am a maintainer of the metric-learn feedstock:
https://github.com/conda-forge/metric-learn-feedstock

Following a new release of the package (v0.6.0) I have updated the recipe based on the automatic PR created following the PyPI update (see https://github.com/conda-forge/metric-learn-feedstock/pull/1). Unfortunately I see that the meta-data of the package (URLs, description, etc) are missing on the [Anaconda page](https://anaconda.org/conda-forge/metric-learn), while it was there for the [previous version](https://webcache.googleusercontent.com/search?q=cache:fsuR-uMB9T8J:https://anaconda.org/conda-forge/metric-learn+&cd=1&hl=fr&ct=clnk&gl=fr&lr=lang_en%7Clang_fr). I initially thought it was because of the missing license_file entry (fixed in https://github.com/conda-forge/metric-learn-feedstock/pull/3 by making a new build) but this did not solve the problem.

Could you kindly help me with this?

Thanks a lot!
Aurelien
