Using this code the first generator does not show the correct amount for gen 1

Problematic code :

Invlist {O2/H2 Generator 1} +ice
Invlist {O2/H2 Generator 2} +ice
Invlist {O2/H2 Generator 3} +ice
Invlist {O2/H2 Generator 4} +ice
Invlist {O2/H2 Generator 5} +ice
Invlist {O2/H2 Generator 6} +ice
Invlist {O2/H2 Generator 7} +ice
Invlist {O2/H2 Generator 8} +ice
Invlist {O2/H2 Generator 9} +ice
Invlist {O2/H2 Generator 10} +ice
Invlist {O2/H2 Generator 11} +ice

Alternative fix: rename the first gen to O2/H2 Generator 01
and the remaining keep the same like this and use this code

Invlist {O2/H2 Generator 01} +ice
Invlist {O2/H2 Generator 2} +ice
Invlist {O2/H2 Generator 3} +ice
Invlist {O2/H2 Generator 4} +ice
Invlist {O2/H2 Generator 5} +ice
Invlist {O2/H2 Generator 6} +ice
Invlist {O2/H2 Generator 7} +ice
Invlist {O2/H2 Generator 8} +ice
Invlist {O2/H2 Generator 9} +ice
Invlist {O2/H2 Generator 10} +ice
Invlist {O2/H2 Generator 11} +ice
