Error when editing under RSPAMD

Hello
When I change these fields in this "Spamfilter policy" function:

Code:

Greylisting level :
SPAM tag level :
SPAM tag method :
SPAM tag method :
SPAM reject level :

I have an error message:

Code:

Incorrect decimal value: '' for column `dbispconfig`.`spamfilter_policy`.`rspamd_spam_tag_level` at row 1

Do you have a solution?
