Issue Weird result when enable / disable spam filter

[nethubonline]

Hi,

Plesk Onyx Version 17.8.11 Update #60

I can't realize when spamassassin is enabled or disabled when I enable / disable spam filter...please see below procedure to repeat my confuse

Test A Step 1:
Tools & Settings > Spam Filter >
Switch on server-wide SpamAssassin spam filtering: Disabled
Apply individual settings to spam filtering: Disabled
Result: Sometimes spamassassin service is enabled sometimes it is disabled. If it is still enabled & running, just go to Tools & Settings > Spam Filter > submit again to disable both

Test A Step 2:
Tools & Settings > Spam Filter >
Switch on server-wide SpamAssassin spam filtering: Disabled
Apply individual settings to spam filtering: Enable
Result: spamassassin service is enabled & running

Test A Step 3:
Tools & Settings > Spam Filter > submit again without change any setting
Result: spamassassin service is disabled & stopped


Test B Step 1:
Tools & Settings > Spam Filter >
Switch on server-wide SpamAssassin spam filtering: Enabled
Apply individual settings to spam filtering: Enabled
Result: Sometimes spamassassin service is enabled & running

Test B Step 2:
Tools & Settings > Spam Filter >
Switch on server-wide SpamAssassin spam filtering: Disabled
Apply individual settings to spam filtering: Enable
Result: spamassassin service is disabled & stopped

Test B Step 3:
Tools & Settings > Spam Filter >
Switch on server-wide SpamAssassin spam filtering: Disabled
Apply individual settings to spam filtering: Disabled
Result: spamassassin service is enabled & running

Test B Step 4:
Tools & Settings > Spam Filter > submit again without change any setting
Result: spamassassin service is disabled & stopped


You can see last steps of both test are just re-sumitting, but different results. Is it a bug or something I missed?
