Actually on closer inspection there’s something a bit weird going on here; piaware thinks that both there is and isn’t a mlat client and dump1090 running. What is this install based on? Have you made any local changes? Do you have more than one receiver?
edit: you have two connections with the same feeder ID, different local IP addresses, and different MAC addresses. Please ensure that you use a different feeder ID for each physical device.
I have several pi’s running
main 1pi in loft to sdrrtl v3 dongle, into triple filter and adsb 1090 filter to antenna
5.1v 2.5a spu
usb fan with seperate psu for it cooling things down

There is some feed-back system to restart things when no data is received.
That system is completely screwed up if you try to feed from two installations under one feeder-id as it will probably disconnect the working system when the “new” system comes up.
One system detects it’s not working properly restarts everything to try to get it working … then they change places … it’s ugly.
So it’s not so strange that it’s working now.
Just remove the feeder-id from one of your systems and the system will get a new id automatically.
Then you can claim that id and have them both running. There are threads on the subject if you need further advice just google “piaware feeder-id” and it should bring up relevant documents.
