Eviews Returns "0001" where it should be 0

[watabehj]

Hello. I have just upgraded from Eviews8 to Eviews9（64bit-version Standard Edition Apr 20 Build）.
Attached please find "test.wf1". There are two series "aaa" and "bbb" in this workfile. These two series have almost identical values, so when I type "show aaa-bbb", it should return zero or near-zero values. However, "0001" is returned in Eviews9, while normal values are returned in Eviews8. I have attached the Excel file "testresult.xlsx" which contains the screenshot of both results.
Thank you in advance for your kind help.

Thanks. This is actually a display bug - if you click on properties, and then change the display to Fixed Characters, you'll see that it is actually zero. We'll figure out why it is defaulting to "period" rather than fixed characters.
