Backup level 'MSSQL:' is obsolete. Change the backup level to logs only and restart

Hello guys . Recently I had a problem with an MSSQL database backup with incremental level 

networker version on both the backup server and client is 19.5.07 

NMM is 19.5 as well 

windows is server 2012 R2 

The backup only works on logs only and full backup .  not incremental or cumulative incremental 

any idea why suddenly it requires me to change to logs only ?  

thanks
