Recovering from SLIP39 shards doesn't work in iancoleman.io/slip39

Using the slip39 python tool (on Ubuntu and on Windows):

These share don't work in https://iancoleman.io/slip39

Shards recover the original bip39 seed using the slip39-recovery tool

(slip39) C:\Users\Petre>slip39-recovery --using-bip39 -m "either helpful acrobat romp cleanup inside syndrome syndrome various destroy helpful lair fatal fridge scatter papa hand nervous golden saver" -m "either helpful beard romp alto hush filter quiet speak fitness crush voter group august evaluate zero omit smart inherit sniff"
seven replace great luggage fox rent general tower guess inside smile sing

Interestingly, recovering BIP39 from SLIP39 shards generated with this tool DID work a while ago (2 months ago or so) on iancoleman.io/slip39

Can you point to another way of recovering the BIP39 seed from the SLIP39 shards generated with this tool?

If there is no other way to recover the shards produced by this tool except by using its own slip39-recovery, this tool becomes the single point of failure.

There is an issue with iancoleman.io/slip39 at the moment, making it impossible to combine SLIP39 shares.
