STEPS TO REPRODUCE

I have a file with filename:
0000.0000.txt

(1) For Find and Replace, I can type:
Find = ^.
Replace = X

When I select "Okay",
the proposed filename appears:
X000.0000.Xtx
Is this correct or incorrect ?

Should the proposed filename be:
X000.0000.txt

(2) For Find and Replace, I can type:
Find = .$
Replace = X

When I select "Okay",
the proposed filename is:
0000.000X.txX
Is this correct or incorrect ?

Should the proposed filename be:
0000.0000.txX

(3) For Find and Replace, I can type:
Find = \A.
Replace = X

When I select "Okay",
the proposed filename is:
0000.0000.txt
Is this correct or incorrect ?

Should the proposed filename be:
X000.0000.txt

(4) For Find and Replace, I can type:
Find = .\Z
Replace = X

When I select "Okay",
the proposed filename is:
0000.0000.txt
Is this correct or incorrect ?

0000.000.txX

(5) For Find and Replace, I can type:
