BUG IN CPU HASHCAT I THINK OR I MISCALCULATED

HeLLo I AM NEW To Hashcat But In My Project I Found That (CPU Hashcat) Is not able to calculate...Or this Is My Miscalculation Somewhere...please if Yes Please Guide me...!! (Bug Or Miscalculation ??)

My project for CPU Hashcat :- Table look up Attack Mode 5

 Example:-
my sha256 hash of 2-aacaca is fa02bbff7a5cf03e199a04b794a5cab1f4cc887849f661ac2a34024f668893d1
---------------------
My Hash File (hash) contains.
fa02bbff7a5cf03e199a04b794a5cab1f4cc887849f661ac2a34024f668893d1

My Table file (Table1) contains. {limited}
 a=aa
a=ba
a=ca
a=da
a=ea

My Dictionary File (Dic) Contains.
2-aaa

So i PUT:- hashcat -m 1400 -a 5 -t Table1.txt hash.txt Dic.txt
It cracked..giving me answer 2-aacaca



-------------
But When I replaced Same Table With Table2 with All combinations of MixAlpha+Numeric
(Table2) File
a=aa
a=ba
a=ca
a=da
.
.
a=AA
a=BA
.
a=9A
a=99

So I PUT :- hashcat -m 1400 -a 5 -t Table2.txt hash.txt Dic.txt
It Didn't Gave Me the answer ???  Why??
