Atlas slots are not unlocked

Hi,

I'm playing standard, redid all maps, so I have all maps unlocked as T16, the map device shows 6 slots, but I tried endgame mech with 5 scarabs, but only 4 slots are working, the rest two is not consuming and adding scarab mechanism, however it's visible

is it a bug, or if we need to unlock again, why are they displayed as unlocked..

Edit: I've experienced this with previous league T16.5 memory maps with Imbued Harvest (scarabs: awakening, harvest doubling, 3 risk scarabs - two of these was not used up). Also tested with updated T16 map with 5 scarabs and there it worked) - so it's either for 3.26 maps or 3.26 memory maps

I guess I missed reading this pass from the changes

"Cartography Scarab of Risk now has a limit of 1 (previously 5)"

everything is clear
