Upon new updates for BP app here is instruction how to fix it:
1) Unpack content of tpk(regular zip archive) to some folder.
2) Go to this folder and find all files in which include bundle id: com.samsung.health.samd.bp... (I used AstroGrep to find all occurrences). Not only xml, but also binary files (bin folder)!
3) Replace all occurrences you found with some different id by changing of 1 character(etc to com.samsung.health.samd.bb).
4) Go bin folder and rename correspondently to your renaming name of the files.
For example:
health-samd-bp-home -> health-samd-bb-home,
health-samd-bp-service->health-samd-bb-service,
health-samd-bp-widget->health-samd-bb-widget
5) Go to root folder again and find all occurrences of health-samd-bp... inside of all files. Replace it with health-samd-bb....
6) Pack all modified files back
7) Sign and install.
