Ok the value stopped being reduced after i turned one bot offline.
so i know which bot is it.
i checked the bot.
this is what gets and removes the record

i take 100 top elements with some criteria from group1.
then i take one random element from that list.
then i remove it from db with its ID.
seems it removes the record from both group1 and group2 thats why both dbs are decreasing (when only one should)
but there are no same records that are in 2 groups simultaneously
can there be 2 records, one in group1,second with group2, that have same ID?
that seem to explain one issue.
But issue number 2 is still not clear whats going on.
Is it just record number bugged : ?

because it should be growing by one every 30 second but its been at this number for a while and eventually goes few up and few down
edit
NVM i was using older version of my bot (i created fixed version but launched wrong shortcut)... what a waste of time !
