I wouldn’t recommend 2.4 rotors the MT7 calipers sit closer than MT5s I have run with 2.3 TRP rotors & Ali express levers similar to new Clark’s brakes. Had issues so Gone back to MT5 levers & calipers better modulation than with Shimano levers which are very on off power. I run the Loic Bruni...
Maybe olive was all good for old levers but not the new ones. It’s just working out what’s changed. Pull off cover to 8mm nut & pull lever few times, any slight oil on hose?
This technique does work not hadoil seeping from bleed screw before only hose at lever or caliper end. Mine have been pulling to bar sometimes where run aftermarket (Ali Express)lever with Magura caliper
Check to see if there is any oil on the hose, around where it joins to the lever it’s might not like the olive & barb used or the 8mm bolt into lever could be nipped up a bit more
