In persistent mode lost Keys.

[hsnamed]

Steps to reproduce:

@Test
    public void lostkeysTest() throws Exception{
        File storagetmp = new File("./tmp.dat");
        if(storagetmp.exists()) storagetmp.delete();
        storagetmp.deleteOnExit();

        LongValue valueSample = Values.newHeapInstance(LongValue.class);
        ChronicleMap<byte[], LongValue> mmap = ChronicleMap
                .of(byte[].class, LongValue.class)
                .entries(10)
                .actualSegments(1)
                .constantValueSizeBySample(valueSample)
                .constantKeySizeBySample(new byte[36])
                .removeReturnsNull(false)
                .createPersistedTo(storagetmp);

        valueSample.setValue(1);
        var lostKey = "12b5633bad1f9c167d523ad1aa1947b2732a865bf5414eab2f9e5ae5d5c191ba00000001";

        var h1add = Hex.decodeHex("591e91f809d716912ca1d4a9295e70c3e78bab077683f79350f101da6458807300000000");
        mmap.put(h1add, valueSample);

        var bLostKey = Hex.decodeHex(lostKey);
        mmap.put(bLostKey, valueSample);

        var v1 = mmap.remove(h1add);
        Assert.assertEquals(1L, v1.getValue());

        var h3add = Hex.decodeHex("6f80ca7441710cf0942cf99e3e8aa59d38d73b124730306afeb1aec8f08fd76b00000000");
        mmap.put(h3add, valueSample);
        //here we lost key
        var lostKeyVal = mmap.get(bLostKey);
        Assert.assertEquals(1L, lostKeyVal.getValue());

        var v2 = mmap.remove(bLostKey);
        Assert.assertEquals(1L, v2.getValue());
}

map stat :

09:02:36.892 [Test worker] DEBUG ChMapTest - Map  segments: 1, size: 2
09:02:36.893 [Test worker] DEBUG ChMapTest -   segment[0] - 2 entries

As we see strange key : <266d63a1>ad1f9c167d523ad1aa1947b2732a865bf5414eab2f9e5ae5d5c191ba00000001
its like <12b5633b>ad1f9c167d523ad1aa1947b2732a865bf5414eab2f9e5ae5d5c191ba00000001 except 4 bytes

Problem arise when map used in persisted mode createPersistedTo
