Dbeaver SQL Common Expression Table Question - sql

Question

I am trying to create a table in Dbeaver and I have encountered an issue. I have posted my code below. My code works fine if a well has completion types of both 'Frac' of 'MSFRAC'.However, this well with a uwi= '100042204410W500' has only 'MSFRAC' as completion type. When I run my code, it shows nothing in output (image 2).I wrote a small part of code at the top to check this well's information and you can see the output shows that all well completion types are MSFRAC.
What cause this empty output issue? As you can see here, I am using common expression tables for key words "FRAC","MSFRAC",and"%PERF". So my assumption is if FRAC and %PERF% has no record for this well, even tho MSFRAC has data, it will cause the output to be empty???
Please help!!!! Much Appreciated1
