Since there seems to be few known bugs in the platform, I think it would be a good idea to have a list that contains allof them so that if you have issues with something you can come here and check if it’s a known bug so you can avoid to waste time fixing it.
Like I just found out that the **“update value” of the data sources database doesn’t work**.
It only accepts certain data, like for example if I try to update to the number zero it doesn’t work, but it accepts zero in string, but it also depends on how I named the column of the db, I don’t know

Hi @maxb, @actech has shared his bug tracker project: [https://x.thunkable.com/projects/5dbd5243a77acad1b26f851f/project/properties/designer/](https://x.thunkable.com/projects/5dbd5243a77acad1b26f851f/project/properties/designer/)
from this thread:

Also, regarding the issue that you found. Here is a possible work around: [The things that worked no longer work](http://community.thunkable.com/t/the-things-that-worked-no-longer-work/600837/2)
Maybe it doesn’t accept 0 because it thinks it means false? I once set a variable as 0 as a place holder and when tested it determined it as false. Not super sure though.

Thank you @mythi for this,
good idea from @actech,
i just remixed it to look a little bit more catalogued in order:
[https://x.thunkable.com/copy/1ecf5a0781c60c6f2baaa7a9f6ad4e10](https://x.thunkable.com/copy/1ecf5a0781c60c6f2baaa7a9f6ad4e10)
I was gonna add my bug of the data sources myself, but it look like I can’t even create a new database

It’s not only about simple numbers, or not making math operations, it just doesn’t save to the database if it doesn’t like the column name, like if I give it a cloned label id to the column ‘Name’, I can save it, but if Igive it to the column ‘Price’, I can’t save it

Ok so, I found the problem,
if you leave the blank spaces in a new row, those column won’t work.
Also the number zero problem seems solved, it was maybeconnected.
(Unfortunately it seems that the **data sources database** , which IS NOT the same as local DB, **is way slower than local DB** making the app unresponsive)
