Need help with Manual Activity Logging

[SunriseRun407]

Bear with me, here's what I am trying to do, it's so simple yet Fitbit managed to screw it up royally:

1. I started exercise tracking prior to doing abs workout, fitbit was accidentally paused (because there's no way to lock buttons), hence showing 20 instead of 40 mins of workout. 
2. I wanted to increase the duration, tried from Android app and then web, can't be done (bug #1 or perhaps just a stupid "feature" - what's the rationale behind this?)
3. So I deleted the entry and tried reentering it from Android app, but I can't pick the same exercise type that i have always been using, my options are limited to some exercise types that do not reflect what I am doing (bug #2) 
4. Then I tried entering it from web interface, I could enter whatever exercise type I wanted BUT it won't show exercise details (bug #3) and it won't sync to Android app (bug #4)

Fitbit team, how can such a simple task become mission impossible? I'm profoundly perplexed... I have researched on the forum before posting, looks like people are having similar problems for years. Here are similar issues that are either unresolved or marked as resolved but the solution doesn't work for me:

• https://community.fitbit.com/t5/Flex/Fitbit-app-isn-t-recognizing-syncing-my-manual-activity-logged/...
• https://community.fitbit.com/t5/Fitbit-com-Dashboard/Manually-Logged-Activity-issues/td-p/1681226
• Reading the last entry, looks like some guy managed to change the exercise name, but it's only doable in Windows 10 app - WTF fitbit team? Why do you create inconsistent feature sets across different platforms, makes absolutely no sense especially when renaming is such a basic feature that is not platform dependent - https://community.fitbit.com/t5/Charge-HR/How-do-I-change-type-of-exercise/m-p/1891190#M173023

• Edit manually logged exercise type - such a basic feature and even though 2491 members have requested it since 2014, Fitbit product team did not prioritize it - https://community.fitbit.com/t5/Feature-Suggestions/Ability-To-Edit-Manually-Logged-Exercise-Type/id...

Fitbit Android dashboard showed total time spent on sleeping last night was 8h23m, which was incorrect as I slept for 5h49m+1h40m. Upon checking the detailed sleep log and returning to dashboard, it will refresh to the correct duration 7h29m. If I exit the app and comes back again, it will show 8h23m again without fail, until I go into the detailed log screen and come back out. WTF Fitbit?First screen: 8h23m

Second screen

Third screen: 7h29m (correct)

All I've been asking since I got this Fitbit in December 18 is a way to track crunches/situps/ab workouts,  which should be part of any exercise program.
