we can't see your return or k-1. you most likely were subject to Passive Activity loss limitation. if you are a passive partner or shareholder the ordinary passive loss (lines 1,2 or 3) shown on the k-1 including any carryover can't exceed current year passive income.
the other possibility is that the K-1 is from a publicly traded partnership (BOX D is checked on the k-1). in this case regardless of your adjusted gross income the passive activity rules apply. deductible passive losses can't exceed passive income items. There will be no 8582 because each PTP stands on its own regarding this rule.
when passive loss limitation rules apply in full at best you end up with a net of zero. thus, like in your case, the ordinary loss on schedule E which flows to schedule 1 line 5 is offset by an equal amount of capital gain form 1040 line 7.
