Merge in Power query editor

I made it,

1. Read data from excel

2. create two reference on first step

3. first reference have min value  QMIN

4. second reference hva max value QMAX

5. Merge QMIN Left Outer Join QMAX

6 In new table I get wrigth values from QMAX

This is frist Query:

QMIN:

QMAX:

From bouth Query remove last two columns, and Attribute Split with "/" separator and replace QMIN with START and QMAX with END:

QMIN:

QMAX:

Merge LEft outer JOin

First Row tabel values:

Everthing is nice with problems.

But After Expand last row, get same Value as from QMIN query:

I schould get from QMAX Value, which is Ok in step before Expand.

I get here same VAlue from QMIN Value column.

Bet regards
