I think this is a bug that's being worked on, try going back an older InDesign version for now.
Thank You Sir,
After installing older version problem is gone. but let me know, when i will install the lastest version?
don't know if you are part of Adobe InDesign Prerelease…
There is a new version of 16.2 available at Prerelease that should address this issue.
If you want to sign in, go to https://www.adobeprerelease.com/ and check in category AVAILABLE PROGRAMS.
( And If you are already part of it you know your way around. )

also add a screenshot of your JPEG export options.
From the supplied JPEG I can see that you exported to 150 ppi. But all the other options are unknown.
From the InDesign document I see that you used InDesign version 184.108.40.206 from Mac OS.
FWIW: I cannot recreate the problem from my InDesign 220.127.116.11 and the latest version in Prerelease.
