All sorts of things wrong here.

I shall assume that you have whitespace before a naked "IN" and in
other places where you should, and that wrapped lines really are single
lines.  Maybe I'll just mention this in passing.

I don't have your original problem in front of me.  I'll have to look
and see if I can find it.

You can't have mutiple definitions for the same zone.

PLUS - don't you have the whole class C?  You have, at least, 52-109.
If you have the whole class C, your zone is "195.141.63.in-addr.arpa".

Comments about line joining and indentation should be obvious.

Likewise.  Now the real problems.

(1) "109.195.141.63.in-addr.arpa." and "52.195.141.63.in-addr.arpa."
are not zones, as far as I can tell.

(2) "109.195.141.63.in-addr.arpa." and "52.195.141.63.in-addr.arpa."
are not the zones that this file is talking about.  These lines will be
seen as declaring subdomains, and delegating those subdomains.

(3) Hence, NO name servers are seen as being in this zone at all!

Per your original mistake, this would have been the only line seen in
this file that was legitimate.

You may see the reasons for the problems now.

Let's try this for your file.  If you had had this before, you wouldn't
even have had to change this when you changed /24 networks.
