bug with multiple {start} {end} pairs

Question

multiple {start} {end} block, when I used, only the first pair effective, all the followings are all failed and have no effect. The examples as follows:

`block1

{start} .....

.....(other sentences)

{end} ....

{start}<->{end} : ...

....(some other sentences)

`block2

{start} .....

.....(other sentences)

{end} ....

{start}<->{end} : ...

`block3

{start} .....

.....(other sentences)

{end} ....

{start}<->{end} : ...

only block1 has effect, other blocks have no effect at all!

Comments

Could you please be a bit more specific with a small real example.

Please also mention the plantuml version you are using.

---

you can just use multiple {start} {end} pairs, only the first pair works, all others have no actions. my plantuml version is plantuml.1.2021.4.jar. BTW, I just announced only once "!pragma teoz true" at the very beginning of the file.
