Sieve: InvalidToken[101]

[dharmann]

I've about 40 filters, with about ten rules for each one.
I've switched from Roundcube, where I've used all that filters without problems.
Now, recreating the SAME filters on Rainloop, after created 37 filters, I'm unable to save the others. If I delete some previously created filter, then I can save the new ones.
Below the error I've got:
