Hi Stella,

Thanks for reporting this.

I am able to normally submit Encounters to MantaMatcher. Can you confirm you were trying to submit an Encounter here?

If so, can you provide us with details and photos of the Encounter so we can try to reproduce?


Hi Jason,
Yes correct. See attached, I’ve tried with different encounters too. I will try on another laptop? See attached for a screen shot.

Hi Stella,

This is only happening with the “unknown” value for species. As a workaround, please select a specific species for your submission. I am working on a fix for “unknown” under our internal work ticket WB-1187.


Hi Stella,

This issue should be resolved now on MantaMatcher.

Thanks for reporting it, and please let me know if you see it again.
