How to validate CRC-32 calculation of Zip file

I want to validate that my ZIP file has a correct CRC-32 checksum.
I read that in a ZIP file the CRC-32 data is in bytes 14 to 17:

Offset  Bytes   Description[30]
0        4  Local file header signature = 0x04034b50 (read as a little-endian number)
4        2  Version needed to extract (minimum)
6        2  General purpose bit flag
8        2  Compression method
10       2  File last modification time
12       2  File last modification date
14       4  CRC-32 of uncompressed data
18       4  Compressed size
22       4  Uncompressed size
26       2  File name length (n)
28       2  Extra field length (m)
30       n  File name
30+n     m  Extra field  

I wanted to validate a CRC-32 checksum of a simple ZIP file I created:

00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00 00                                            | ..

The CRC-32 is: 0x4C18C78C
I went to this CRC-32 online calculator and added the following un-compressed row from the file:

50 4B 03 04 14 00 00 00 00 00 38 81 1C 51

This is the result:

But none of them equal to: 0x4C18C78C.

What am I doing wrong? The CRC-32 of the ZIP is the calculation of all the bytes (0-13) before, no?

I was able to create a zip file that matches the one in the question. The header shows that the compression type == 0, which means no compression, the uncompressed size == 2, the data == {73 73}. CRC32 uses reflected input and output, and the CRC is stored in little endian format, so the CRC == 0x8CC7184C.

I get a match using CRC32 on data of {73 73} using this online CRC calculator:
